[MFD] Overall MFD Document

[MFD] Overall MFD Document

Hi Bill,

I haven't got any time this week to explore the latest
SM/2.0 XML schema, but...

If the power elements aren't named and scoped
exactly like the PWG Power Mgmt Model, then
the MFD Overall (and the XML Schema) should
be corrected accordingly.  Power Model places
normative requirements on the representation
of the power elements in XML schema.

(I know Pete took these elements first from Power
MIB, not the Power Model - in both, several of the
properties have been renamed since November
for clarity and some properties have been added)

Cheers,
- Ira
