RE: xml:href, xml:rel and xml:type
I agree that is how it has traditionally been considered. We had to wrestle with this problem in WS-Calendar, in which services are scheduled and service entry points and XML documents are intertwined with iCalendar information (RFC5545) in ways compatible with xCal (RFC6321). The use cases to extend this model using ITIP-based syndication are many and varied. We came up with an ugly substitution group in which an interval can contain a payload (application-specific xml derived from an abstract calendar type), OR an XLINK (if the reference was to somewhere else) OR an XPATH (so the reference could be to somewhere else in the same message / document set) OR an XMLANY. The XPATH approach is most desirable when used as part of messaging-based communications, while the xlink approach makes more sense for RESTful approaches. That portion of the spec epitomized the aphorism that standards work is the selection between the odious and the unpalatable. IF there is work to codify / clean up /improve XLINKs, THEN this should be part of the use cases.

I don't think I understand your message. I'm not talking about addressing within a document but between documents, on the web, using URIs. I don't think XPath is in scope in other words.
