BPMN21 — Section 10.2.3: Task description needs revisiting

Description of issue: The description for Task needs revisiting

• States that "A Task is used when the work in the Process cannot be broken down to a finer level of details". This doesn't reflect typical usage. It's not that it cannot be broken down, but rather many users simply choose to not break down further. Users model at the level of detail most appropriate for their needs and the needs of their audience.
• States that "Generally, an end-user and/or applications are used to perform the Task when it is executed". What does this mean? A black-box Task is traditionally used for documentation processes, where what the task does is more important than how (whether by an end-user or by an application) it is done. If users know how it should be done then they would use a specialized task (i.e. User Task or Service Task) rather than Task

Proposal: Reword to make it clear that Task has a purpose and usage in itself, beyond being a superclass for specialized tasks.
