The <task> element is the top-level element for a task topic. Tasks are the main building blocks for task-oriented user assistance. They generally provide step-by-step instructions that will enable a user to perform a task. A task answers the question of "how to?" by telling the user precisely what to do and the order in which to do it. Tasks have the same high-level structure as other topics, with a title, short description and body.

Note: Beginning with DITA 1.2, there are two task models available in the DTD and Schema packages distributed by OASIS. One model, referred to as the general task, allows two additional elements inside the task body (<section> and <steps-informal>); it also allows multiple instances and orders for each element within <taskbody>. The second model, referred to as the strict task, maintains the order and cardinality of the DITA 1.0 and 1.1 taskbody. This strict task is implemented in the DTD and Schema with a constraint module.

See the taskbody description for additional details about the two models and for a description of impacts to DITA 1.1 documents.


Note: These models represent only the default document types distributed by OASIS. Actual content models will differ with each new document type.
