Yes, but it could occur the same as in the example I provided. A XML document contains a reference to other node of same or different document: <external anchor="http://xcap.server.org/document.xml/~~/root/child"; /> Then the client knows that the default namespace for the application is "urn.default" so it must transform the above Xpth segment into: xpath( "/ns:root/ns:child", "ns"=>"urn.default" ) For this, the client must do a dirty parsing of the Xpath expression. > In fact, I don't understand why XCAP does not simply use XPointer. SIP/XCAP RFC's are mostly written by non real developers, so they don't care how easy are these specifications to implement. In fact, by adding some "extra-non-useful-but-cool" features on top of an existing specification the RFC author seems to "provide some added value..." :( -- Iñaki Baz Castillo <[email protected]> _______________________________________________ xml mailing list, project page http://xmlsoft.org/ [email protected] http://mail.gnome.org/mailman/listinfo/xml
