DTD, XSD and sample XML header docs

[Christopher Ferris <chris.ferris@east.sun.com>]

All,

Okay, I've been meaning to get this done for a while now.

Here are the "level1" DTD, XSD and sample XML documents
based on the "published" header spec.

Your comments and feedback are welcomed. I have added a
few annotations to spice things up a bit and generate some
discussion.

Most notably:
	- do we need ReliableMessagingInfo if we have a TSLA
	- Should the PartyId be expressed as elements or as
	follows:
		<!ELEMENT PartyId (#PCDATA)>
		<!ATTLIST PartyId context CDATA "Undefined">
	or optionally:
		<!ELEMENT PartyId #EMPTY>
		<!ATTLIST PartyId 
			context CDATA "Undefined"
			uri CDATA #REQUIRED>
	of course, URI should have its own built-in context, so it
	isn't clear that the context attribute adds any value. 
		e.g. uri:duns:12345

Anyway, keep those cards and letters coming;-)

Chris
