Good editing suggestions. We'll add them to our list of changes.

You bring up the point of many use cases having requirements listed with
them, including "requirements" that the working group didn't approve.
This is an unfortunate side-effect of not having enough time to edit the
use cases before the document was due. We will go through the use cases
and straighten this out.

ACTION: Remove requirements from the individual use case sections.
Update requirements and objectives to link to any use case that listed
