DITA Element Reference

This specification has been replaced by Mallard 1.1.

This page lists elements in DITA and provides recommendations for equivalent or similar functionality in Mallard, when available. This list includes elements that are specializations of other elements, because sometimes more specific recommendations can be made for specializations than for base elements.

Some specialization domains provide functionality that has no equivalent in Mallard, or for which a single recommendation can be made. The following domains do not have their elements listed explicitly:

bookmap
classify-d
glossentry
hazard-d
indexing-d
map
mapgroup-d
mitask-d
subjectScheme
xnal-d

This page does not list elements used in a DITAVAL file. Conditional processing is not addressed by the core Mallard specification, although extensions may provide this functionality. Additionally, this page does not list any of the highly specialized learning and training elements.

In general, Mallard does not attempt to model data as explicitly as DITA. Mallard allows elements and attributes from external namespaces and allows a style attribute on all elements. These mechanisms are preferred when additional semantic information is needed for tracking or validation.

abbreviated-form	No equivalent in Mallard. Future versions may address glossaries directly.
abstract	No equivalent as a block element. Use block content instead. For link preview text, Mallard provides this separately from the block content using the informational desc element.
