|Information types / Task|
The general task information type was introduced in DITA 1.2 as a less prescriptive alternative to the task (or strict task) information type.
Task information types in base DITA 1.2
For documenting most procedures, the strict task is the more appropriate choice. Conceptually, it is best to think of the task information type as meaning strict task. The strict task information type is the equivalent of the DITA 1.1 task, while the general task has much more relaxed content rules.
Wherever possible, you should prefer the strict task. If your organisation's content model is more appropriately served by general task, then stick to general task across the document repository. Avoid mixing strict task and general task in the same publication.
