Chris:

Thanks for your due diligence. I will update the schema to reference

http://www.w3.org/2001/xml.xsd

plus add a comment that some parsers may require the declaration:

xmlns:xml="http://www.w3.org/XML/1998/namespace"

Regards,
-Arvola

A couple of points. I'm glad that this was found.
At the time of the ebXML 1.0 specs, (at least the
time when the authoring was on-going) this didn't
exist, hence the reference to an oasis-open.org URI.

However, I just tried resolving the URI that Arvola
would like to refrerence and I get a 403. I imagine
that this is probably not desireable.

Suggest instead that the URI referenced be:

http://www.w3.org/2001/xml.xsd

Cheers,

Chris
