Uhh, our charter says "The framework proposed must support the kind of
extensibility actually seen on the Web: disparity of document formats and
protocols used to communicate... "

That sounds like "protocol neutral" to me.  I can assure you that issues
that challenge fundamental assumptions expressed in our charter will get no

Anyway, what you are be saying seems to be empirically false, as I may have
mentioned once or twice previously :-)   There are definitely firewalls out
there that operate at the level of XML message content irrespective of the
protocol used to deliver it. The WSA document does (or at least will, when I
get done pasting various text from the public list into the document)
accomodate this.  Therefore, I assert that it is clearly NOT impossible for
an architecture to be both protocol neutral and have its messages get past
firewalls.  If we are disagreeing about the definition of "firewall" so be
it, but you're going to have to clarify that.
