Actually, this brings up something I've been thinking about for a while. It is typical to think of an XML document as being a self-contained entity, which makes sense from an XPath perspective, but once you start thinking about databases of XML documents, this does not always hold true. Indeed, in that context, even XLink is predicated upon using a URI that also bears function as a URL. (xlink:href="" Yet even this is local to the database in question. Once this document leaves the domain of that database, then the @xlink:href link becomes meaningless. This points to the need for a global identifier as a data-type, one likely based on xs:anyURI, that nonetheless has the specific semantics of a weak identifier (the assumption then being that there exists a target for an IDREF, but that target may not in fact be within the accessible context for that resource.
