[MFD] Issue for MFD teleconference Thursday 10/29?

Hi Pete,

I agree that we can administratively improve the visibility
of our free-standing Requirements specs.

But I still think the "last year's news" effect of a static external
Requirements spec is a real downside.

In the Power Management Model, there has been repeated
update of Requirements in both Use Cases and Design
Requirements sections.

And relevant Use Cases are important and evolving, by their
very nature.

Cheers,
- Ira
