ACTION: Rich to begin work on schema

It's a lovely Friday afternoon.  What better way to spend some moments 
than with W3C XML Schema? :)

Attached is a schema for the current ws-addressing documents.  Actually, 
just the core, since I couldn't figure out how to do the WSDL bindings 
(and I'm willing to wait until a future draft for those), and the SOAP 
MEPs don't really have anything to schema-cize.

I do have one question (three, actually), and they're marked by XXX in 
the document.

We can perhaps close this action; I believe ongoing maintenance is an 
open issue, or agreed to be left to the document editors.
