do you have pointer?

Ok, Roy, so using my model or Sandro's, show  why when you
try to describe caching it breaks.

If you have it in the form of a formal system, then I think
a pointer to it would be very interesting.   I know Dan Connolly did
some work in Larch, but if you have a very much more complete
analysis, that's great. Do you have a URI for it?

I have asked you to refer to individuals -- there has not been a
combined approach to this from W3C people.  Sandro is an MIT/LCS staff
member working on Darpa funded research. David Booth is an
employee of HP and a W3C Fellow. You are a member of the
Technical Architecture Board. But we are all individuals too.
