<taskbody> element is the main body-level element inside a
task topic. A task body is designed to contain information specific to completing a task, such
as prerequisites, contextual information, and steps. DITA 1.2 introduced a much looser
<taskbody> content model in order to allow for more variations in
the structure of a task. A constraint module was also provided in order to maintain
compatibility with the previous strict model; this constraint is used in the default task
distributed by OASIS.
<steps-informal>); it also allows multiple instances and varying order for the
<section>elements. The strict task model maintains the order and cardinality of the DITA 1.0 and 1.1
<taskbody>content model. This strict task is implemented with a constraint module.
Authors that use the default task DTD or Schema provided by OASIS will continue to see the strict task model when upgrading to DITA 1.2 or DITA 1.3. Authors wishing to use the general task model will need to migrate their DITA 1.1 documents to reference the general task document type shell.
document type shells that include the task module as-is, or that specialize
<task> element without specializing
<taskbody>, will also
need to include the strict taskbody constraint module in order to
maintain the order and cardinality of prior DITA versions.
Task specializations that specialize the
<taskbody> element will not be
affected by the new model, although they can be updated
as needed to take advantage of the new elements.
See appendix for information about this element in OASIS document type shells.
