Task

The OASIS DITA Technical Committee distributes two varieties of task topics: general task and strict task. Both task topics serve the same purpose: to provide users with comprehensive instructions for performing a task. Their content models vary, however.

General task
Has a more relaxed content model. It allows <section> and <steps-informal> inside of the task body; it also allows multiple instances and varying order for the elements that make up the task body.
(Strict) task
Maintains a strict order and cardinality for elements within the <taskbody> content model. The strict task is implemented with a constraint module.
