B.1.1 Changes from DITA 1.1 to DITA 1.2

(Non-normative) DITA 1.2 adds a number of new features to DITA, including indirect addressing via map-defined keys; the ability to define content-model constraints for DITA document types; specializations for learning content and the machine industry; and taxonomies, ontologies, and controlled vocabularies. Other refinements include extended markup for glossaries and terminology.

B.1.1.1 New features

The following features are new in DITA 1.2:

B.1.1.2 New element types

The following base element types are new in DITA 1.2:

<text>

Allowed in most contexts where text is allowed but neither <ph> nor <keyword> are allowed. Enables reuse of text in almost any context.

<bodydiv>

Allows creation of untitled containers within topic bodies. Intended primarily for specialization.

<sectiondiv>

Allows creation of untitled containers within sections. Intended primarily for specialization.

<keydef>

Topicref specialization for defining keys. Sets the default value for the @processing-role attribute to "resource-only".

<mapref>

Topicref specialization for referring to DITA maps. Sets the default value for the @format attribute to "ditamap".

<topicset>

Used to define sets of topicrefs that represent an atomic unit of reusable navigation structure. Requires the @id attribute be specified.

<topicsetref>

References a <topicset> element. Enables preservation of the identity of the referenced topicset.

<anchor>

Defines a point within a map to which topicrefs can be bound using the <anchorref> element.

<anchorref>

"Pushes" one or more topicrefs onto an anchor point defined by an <anchor> element. Similar to a conref push but allows the relationship to be managed dynamically by the renderer.

B.1.1.3 Refinements to maps
B.1.1.4 Refinements to content references
B.1.1.5 Refinements to topic elements
B.1.1.6 Refinements to specialization
