I suggest removing the words "to the greatest extent possible".  All goals
are to the greatest extent possible.

I'd like to remove the word "existing".

Generally "web" is capitalized.

I'm dubious about the success factors.  They seem to be an attempt to
summarize the principles of the web architecture from an "ilities" and a
technical spec perspective.  These things are up to the TAG to
document/define.  I would suggest that the critical success factors should
be more along the lines of:

CF1: The Web Services reference architecture complies with the architectural
principals and design goals of the Web:
CF1-A: as defined by the work products that the TAG produces that define the
web architecture.

This allows us to use documents, findings, review notes, etc. from the TAG.
It also allows us to ask the TAG what it thinks of our compliance, then they
can issue documents/findings that detail our compliance.  I believe that a
critical success factor will be whether or not the TAG deems that web
services fit in the web architecture.

If you want to make a more explict CF along the lines of
CF1-B: and as a result of solicited review by the TAG.

I'm ok with that too.

Cheers,
Dave
