Equally important to defining the rules and yet much more challenging
is defining a viable mechanism (or at least the requirements for such
mechanism) to enforce the rules.  I for one would like to see W3C
accomplish what IETF couldn't in dealing with intermediaries in ways
that can *safely* allow for intermediary processing -- which inevitably
results in altering data byte wise -- without setting off yet another
end-to-end religious war.  

On defining rules, perhaps we should strive to achieve an ultimate
goal: a standards rule set to render any given SOAP document in a
canonical form.  E.g. parserA and parserB may exercise different
features on a SOAP doc, but they MUST produce the same output if
the rule set kicks in.
