Change pbs.preferred-term from single cardinality to one-or-more cardinality in pbs.mp.content, pbs.mpuu.content, pbs.mpp.content, pbs.tp.content, pbs.tpuu.content, pbs.tpp.content and pbs.ctpp.content Change cardinality of pbs.ex-manufacturer to one-or-more in pbs.tpuu.content and pbs.tpp.content. This is to include PEMP. Change cardinality of pbs.block-container to one-or-more in pbs.indication.content.
Business. To support Use Cases that involve data that is non-effective.	3.0.a8 21 August 2015	Redesign temporal data module.	Change Rename pbs.histories-list to pbs.previous-list and pbs.history to pbs.previous. Replace effectivity and history attributes with previous attribute. Changed textual description in references to include effective date and code. This is to support temporal data in references. Add Add pbs.effective to all PBS elements that contain complex content. Add pbs.effective and either pbs.amount or pbs.value to all PBS elements that contain simple content. Add pbs.moved to anchor elements that have been deleted or relocated. Added pbs.code, pbs.effective to pbs.dispensing-rule-reference.content. Remove Text from pbs.dispensing-rule-reference.content.
Business. Improve support for increased quantities.	3.0.a8 21 August 2015	Moved increase information to benefit type. This is so that different increases may be specified for different prescriber types.	Add pbs.increase to pbs.benefit-type.content. Remove pbs.increase from pbs.ready-prepared.content, pbs.infusible.content, pbs.standard-formula-preparation.content and pbs.extemporaneous-preparation.content.
Business. To better support use of determined quantities.	3.0.a8 21 August 2015	Simplified pbs.number-repeats.content and pbs.maximum-prescribable.content to better represent determined quantities.	Change Changed textual description in a determined quantity to be optional. This is due to textual descriptions not always being specified. Added optionality to pbs.block-container in pbs.determined.content.
Technical.. Simplify schema.	3.0.a8 21 August 2015	Removed redundant prescribing texts since they are included in the prescribing rule or restriction.	Remove Remove pbs.prescribing-text-references-list from pbs.ready-prepared.content, pbs.infusible.content, pbs.extemporaneous-preparation.content, pbs.standard-formula-preparation.content and pbs.drug-tariff.content. Removed pbs.prescribing-text-references-list from pbs.increase.content.
Technical. Improve representation of data type.	3.0.a8 21 August 2015	Change definition of data type for pbs.limit to a more precise definition of the value of this element.	Change Changed pbs.limit.content to decimal data type. This is a more precise definition of the value of this element.
Technical. Improve management of elements.	3.0.a8 21 August 2015	Unit of measure is specified as a separate element, instead of as an attribute. This allows the unit-of-measure of an object to be managed separately to the content of the product or ingredient.	Add Added pbs.unit-of-measure. Included in pbs.container-definition.content.
Business. Provide additional information for changes.	3.0.a7 26 June 2015	Add the reason element to changes. This allows the reason for a change to be given both textually and also as a terminology concept, i.e. in a machine-readable form.	Add Add pbs.reason element. Replace pbs.all.blocks with pbs.reason in pbs.effective.content, pbs.non-effective.content and pbs.supply-only.content.
Technical. Changes to accommodate temporal data design.	3.0.a7 26 June 2015	Make certain elements repeatable in their parent element so that non-effective versions of the data can be retained.	Change pbs.organisation-reference in pbs.tpp.content.
Technical. Temporal data design.	3.0.a7 26 June 2015	Replace the use of DocBook elements with either PBS-specific elements or container elements. This is to better manage the history of textual content. Adding history attributes to DocBook elements would require the use of 'foreign' attributes in that namespace. This means that DocBook elements, as well as other namespaces such as SVG, are treated as simple content for the purpose of mantaining history.	Add pbs.preferred-term pbs.contact pbs.info to pbs.prescribing-rule.content db.citation to pbs.info.content Replace db.title with pbs.preferred-term in pbs.prescribing-rule.content, pbs.mp.content, pbs.mpuu.content, pbs.mpuu.content, pbs.mpp.content, pbs.tp.content, pbs.tpuu.content, pbs.tpp.content, pbs.ctpp.content db.title with pbs.title in pbs.organisation.content DocBook elements in pbs.organisation.content with pbs.contact Remove db.citation from pbs.standard-formula-preparation.content and pbs.drug-tariff.content Change pbs.value.content to allow any mixed content. This allows the history element to contain previous values containing elements (DocBook, SVG, etc) as well as data values.
Technical. Reduce the size and complexity of the schema.	3.0.a7 26 June 2015	Remove unused or redundant elements.	Remove db.title and db.subtitle from pbs.container-definition.content, pbs.extemporaneous-preparation.content, pbs.standard-formula-preparation.content, pbs.drug-tariff.content. db.subtitle, db.titleabbrev from pbs.organisation.content. pbs.administration (now represented by a group).
Technical. Improve sample data.	3.0.a7 26 June 2015	Set the default dispensing rule for a program.	Change Set the default dispensing rule for a program.
Technical. Support for temporal data.	3.0.a6 12 June 2015	Add the effectivity attribute for use in all PBS elements. This allows a quick method of checking the status of an element, instead of looking up the corresponding history element.	Add effectivity attribute Add effectivity attribute to pbs.opt.xml.attributes and pbs.req.xml.attributes.
Technical. Simplify and reduce the schema.	3.0.a6 12 June 2015	Remove obsolete elements.	Remove pbs.changes-list pbs.change pbs.addition pbs.alteration pbs.deletion pbs.previous pbs.advance-notice
Technical. Simplify the schema by eliminating redundancy.	3.0.a6 12 June 2015	Remove title from medication chart type definitions. This information is contained in the PBS terminology.	Remove Remove db.title from pbs.medication-chart-definition.content and pbs.chart-category.content.
Policy. AHI was introduced with the Sixth Community Pharmacy Agreement.	3.0.a6 12 June 2015	Change the definition of a markup band to support the AHI fee. The structure of markup bands is normalised; all markup bands have a fixed and a variable component, but these components may be set to zero.	Add pbs.offset pbs.fixed pbs.variable Remove pbs.value from pbs.markup-band.content Change Remove optionality from pbs.limit in pbs.markup-band.content.
Business. Add support for Use Cases that involve temporal data.	3.0.a5 15 May 2015	Updated temporal data module. Added support for entity history. Changed to out-of-band model exclusively.	Change Renamed pbs.effectivity to pbs.history. Add pbs.effective pbs.supply-only pbs.date Remove pbs.changes-list pbs.change pbs.addition pbs.alteration pbs.deletion pbs.move
Business. For complete support of AMT.	3.0.a5 15 May 2015	Added CTPP concept. For completeness against the AMT data model.	Add pbs.ctpp
Business. For better support of pricing.	3.0.a5 15 May 2015	Rename element pack-price to pharmacist. "pack-price" only applies to TPP concepts, but this pricing concept may be applied to TPUU (or other) concepts. This improves how product listing information is applied to infusible listings.	Change Rename pbs.pack-price to pbs.pharmacist.
Technical. To reduce the size and complexity of the schema.	3.0.a5 15 May 2015	Remove unused elements, to reduce the size of the schema.	Remove pbs.name pbs.unit
Business. To support change to AMT data model.	3.0 Drafts 1-4 01 May 2015	Change drug data model to support AMT version 3. The version 2 schema described drugs as a strict hierarchy (MP-<MPP-<TPP). The version 3 schema describes drugs as a graph. The drug concepts are listed in a flat pool of concepts and then each concept is linked to its related concepts. This is similar to the AMT v3 data model. The PBS XML Schema now includes most of the "notable classes" from the AMT v3 logical data model (the exceptions are Ingredient and CTPP).	Add to pbs.drugs-list.content pbs.mpuu pbs.mpp pbs.tpuu pbs.tpp Change Change pbs.drugs-list.content to include all drug elements and remove pbs.info. Add Add corresponding reference elements to drug element content models.
Business. Redesign restrictions and authorities to support new Use Cases.	3.0 Drafts 1-4 01 May 2015	Change restriction and authority data model. All restrictions, notes and cautions are generically described as "prescribing texts". The new restriction model separates the restriction from authority information. It also separates legally-binding text from informational text. The latter are "administrative advice", "foreword" and "caution". The former are "restriction", "prescriber instruction", "definition" and "criteria". The manner in which a prescribing rule is restricted is now encoded in the pbs:benefit-type element. For authority-required restrictions the method by which the prescriber contacts DHS (the "channel") has been removed. The benefit-type represents how the prescriber assesses whether the medicine can be prescribed and how DHS assesses the application for authority. The benefit-type also specifies which class of prescriber may prescribe the medicine; previously encoded as "prescriber type". Support has been added for SNOMED-CT codes. The structured representation of restrictions has been redesigned. These are composed of "criteria" and "parameters". Criteria and parameters are linked using logical operators: "all" ("AND" of the components), "any" ("OR" of the components) or "one-of" (one and only one of the components). Parameters are the primitive concepts of restrictions and are generally statements that must be true (or questions that may be answered "yes" or "no). Parameters are closely related to concepts in the PBS terminology, and indeed may be implemented as a concept. Facets have been added to parameters to allow the specification of constraints on data values. These are modelled on XSD data type facets. Increases are moved from restrictions to be a part of the prescribing rule content model. An increase may also be associated with a circumstance.	Change Rename rwt.restriction-references-list to pbs.prescribing-text-references-list Rename rwt.restrictions-list to pbs.prescribing-texts-list Rename rwt.restrictions-list to pbs.prescribing-texts-list Rename rwt.circumstance to pbs.criteria Rename condition to condition-parameter Add Add prescribing text to pbs.extemporaneous-preparation.content and pbs.standard-formula-preparation.content pbs.all, pbs.any and pbs.one-of pbs.treatment-phase pbs.benefit-type pbs.maxInclusive, pbs.maxExclusive, pbs.minInclusive, pbs.minExclusive Remove rwt.alternate-text rwt.authority-method g2g.eauth g2g:total
Technical. To make the schema simpler to use.	3.0 Drafts 1-4 01 May 2015	Merge XML namespaces and element vocabularies. This is to make the schema more easy to use.
Technical. To make the schema simpler to use.	3.0 Drafts 1-4 01 May 2015	Remove XML Namespaces that were only used for managing controlled vocabularies. Controlled vocabularies have been replaced by concepts in the PBS terminology.	Remove XML namespaces rwt g2g int, rwti change contrib admin auth form incentive fee markup copay sn group container dr atc
Technical. This section is experimental.	3.0 Drafts 1-4 01 May 2015	Support temporal data. Merge the previous month delta with effectivity data. Allow the complete history of changes over a period of time, say twelve months, to be published.	Add Add pbs.history to all content models. Add pbs.value to simple content models. Remove pbs.changes-list Change Rename pbs.effectivity to pbs.history
Technical. This section is experimental.	3.0 Drafts 1-4 01 May 2015	Introduce the PBS terminology using RDF and OWL. This replaces controlled vocabularies. Element subtyping is implemented as references to PBS concepts. Groups are reimplemented using PBS terminology. Concepts in the PBS terminology are able to represent boolean values, i.e. elements that are either present or not. Replace controlled vocabulary values with URIs that refer to a concept in the PBS terminology. This particularly applies to how elements are subtyped. Subtyping is acheived by reference to a PBS concept.	Remove pbs:not-to-be-broken pbs:continued-dispensing pbs:medication-chart pbs:counted pbs:groups-list pbs:group Remove scheme attribute from pbs.code.attlist. Change Add rdf.resource attribute to pbs.code.attlist. Replace type element with rdf.resource attribute. Modify pbs:member-of to use the rdf.resource attribute. Add Elements and attributes from the RDF and OWL W3C standards.
Technical. Reduce complexity of the schema and make processing easier.	3.0 Drafts 1-4 01 May 2015	Rationalise pricing data structures. Make the concept of "product listing" more explicit. This allows the ready-prepared and infusible pricing models to use the same data structure. This allows easier processing of pricing information. Pricing data is denormalised, which makes processing easier at the expense of increasing data volume. Rationalise description of what the maximum may be prescribed for ready-prepared and infusible pricing models. Allows maximum prescribable and/or number of repeats to be described. For use where a maximum prescribable or number of repeats is a determined quantity.	Add pbs.product-listing Add pbs.dispensing-rule to pbs.price.content Add pbs.ex-manufacturer to pbs.lowest.content. Remove pbs.prices pbs.tpp-list dispensing-rule attribute from pbs.price.attlist Change Rename pbs.dispensing-rule to pbs.dispensing-rule-definition Rename maximum-quantity to maximum-prescribable Modify pbs.maximum-prescribable.content and pbs.number-repeats.content to have element content.
Business. Support Use Cases involving non-effective items.	3.0 Drafts 1-4 01 May 2015	Improve temporal data. Introduce the notion of 'supply-only' items.	Add Add pbs.supply-only to pbs.effectivity.content. Change Change content model of pbs.effectivity.content to be more general/flexible.
Technical. Simplify the schema.	3.0 Drafts 1-4 01 May 2015	Generalise the specification of data values that apply to the entire Schedule or to individual Programs.	Add Add pbs.values-list to pbs.listings-list.content. Change Rename pbs.copayments-list to pbs.values-list.
Technical. Reduce the size and complexity of the schema.	3.0 Drafts 1-4 01 May 2015	Simplify the schema by removing redundant element types. The context of the element specifies what content is being represented.	Change Replace pbs.pack-content and pbs.vial-content with pbs.content. Remove Remove vocab-version attribute from pbs.root.attlist.
Technical. Allow easier interpretation of data, based on feedback from vendors.	3.0 Drafts 1-4 01 May 2015	Dispensing Rules are named, rather than identified by a URI. Reduce the size of the schema and rationalise the use of XML namespaces. Allow more extensibility in the definition of a dispensing rule.	Add Add pbs.name to pbs.dispensing-rule.content. Remove Remove about attribute from pbs.dispensing-rule.attlist.
Technical. Reduce the size and complexity of the schema.	3.0 Drafts 1-4 01 May 2015	Reduce the number of elements in the schema. The counted element is represented by group membership instead, via PBS terminology. Use DocBook paragraphs directly instead of using a pbs.note wrapper.	Change Replace days element in pbs.safety-net.content with pbs.duration. Replace counted element with pbs.member-of-list. Remove Remove pbs.note and replace with pbs.all.blocks.
Technical. To support Uses Cases involving temporal data.	3.0 Drafts 1-4 01 May 2015	Add a new change element that allows changes where elements are being reordered to be represented.	Add Add pbs.move to pbs.change.content.
Technical. Reduce the size and complexity of the schema.	3.0 Drafts 1-4 01 May 2015	Simplify element structures and remove redundant definitions.	Remove pbs.classification pbs.moa-value pbs.choice pbs.combine pbs.wholesale-price pbs.preferred-term db.state pbs.person pbs.authorisation pbs.transclude.link Change Simplify pbs.administration.
Technical. Improve usage of data.	3.0 Drafts 1-4 01 May 2015	The semantics of the value in a markup band are incompatiable with the "amount" element.	Change Replace pbs.amount with pbs.value in pbs.markup-band.content.
Business. Include metadata for AMT releases.	3.0 Drafts 1-4 01 May 2015	Allow the release of AMT to be included.	Add Add dct.references to pbs.info.content.
Business. Provide capability to include images and diagrams.	3.0 Drafts 1-4 01 May 2015	Add SVG images. This allows diagrams and images to be embedded in the PBS XML document.	Add Add SVG 1.1 schema. Add svg element to pbs.all.blocks.
	2.10.2 04 February 2015	Modified rwt.restrictions-list.content, rwt.caution patterns. These patterns were causing ambiguity when translated into an XSD schema definition.
