One clarification. By this statement:

    All the XPath functions

I mean all the XPath functions that I list below (doc, unparsed-text, etc)

Thanks Martin Honnen for catching this!

Subject: The use of URLs in the XML technologies to reference external resources

Hi Folks,

The XML technologies use URLs to reference external resources. For example, XML Schema uses a URL in the <xs:include> and <xs:import> elements to reference other XML Schema documents.

The below list shows several XML technologies  and where they use URLs. Please let me know if I have missed any place where URLs are used in these technologies to reference external resources.  /Roger
