Thanks for doing this, it is an excellent "strawman".  Let me
take a few whacks at it ... If I don't mention something,
it means I generally agree with the point as written.

Isn't that a pretty ambitious goal for a "reference architecture"?
I would think that only the *designs* of software could be
consistent in that they refer to the same concepts e.g., 
"a Web service endpoint" in the same way.

Again, I just don't see how a "reference architecture" could 
hope to do this.

Here, we need to be more specific about what "security means."

I'd suggest that there's no point in mentioning what we cannot
control.  If we do a good job on the other goals, and
implementers find it useful, it will be evolve in a predictable manner.
If not, it will end up in the bitbucket of history, end of story.

The highest priority, IMHO.

I'd suggest that the point is to come up with coherent architecture
for web services that uses what is valuable from the semantic web
initiative and web architecture principles, but doesn't treat them
as formal constraints.  It is possible (HIGHLY unlikely, IMHO) that
a coherent and consistent web services architecture could "violate"
some of the web architecture principles as we think we understand them 
today.  To constrain this group too heavily by the current understanding
views on the subject could lead to some quasi-religous debates rather than
a two-way dialog to clarify both the web architecture and web services 
architecture in a fruitful way.  A casual glance at the xml-dist-app or
xml-dev archives should give one reason for caution on this subject.
And a casual glance at the trade press this week should give us pause
about formally tieing the web services and semantic web activities 
together!

Another EXTREMELY high priority goal IMHO.
