Mike, 

If you provide us with a list of necessary changes, we can discuss
them and make them part of the AD review process.

We are definitely looking to eliminate nice-to-have changes and
proposed mib review requirements that are not currently included in
the mib-review-guidelines-03. 

[soapbox]
Working against constantly moving targets is one major reason why
these documents have already taken three years. If it wasn't defined
as a requirement when we started WGLC, I don't want to hear about it
now.
