XML Question

OK. I have not yet had to pay much attention to these XML DTD / name space
issues - so help me out on this. AFAIK the name space is defined in the
header of the XML, i this case the standard Atom header:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:content="
http://purl.org/rss/1.0/modules/content/" xmlns:wfw="
http://wellformedweb.org/CommentAPI/" xmlns:rdf="
http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="
http://purl.org/dc/elements/1.1/" xmlns:cc="http://web.resource.org/cc/">

So my guess is that this would work in Rev if i tell the external how to
interpret the name spaces by pointin it to the DTD. however changeing the
revXmlcreateTree function to be strict and not ignore badly formed XML makes
no odds - and there does not sseem to be a way of hooking the external up to
the external DTDs other than a simple check.

This is a standard Atom feed - the XML name spaces are defined in the
headers with valid DTDs - or am I missing something?

I am not really able to comment on this knowledgeably. I'd be pretty
confident it is all standards compliant - but that is relying on the source
and my scattered reading around XML DTDs. From a user point of view - you
want to make it as easy as possible to parse the most common XML feeds out
here. It looks bad if it breaks with Atom feeds, and bad = bug in my
