I can use either an IDREF or an XPointer (within an XLink, or otherwise) to define a reference by ID to another element in the same XML document, but there are differences: * The syntax is different ["idval" versus "ID(idval)" or "#idval"] * I can have several IDREF attributes in an element, but only one XLink attribute * A dangling IDREF is an error; a dangling XPointer is not That is what I mean by saying the two facilities are incompatible. Or to put it another way, once I have made a design choice to use IDREF or to use XPointer for the links in my documents, I am stuck with my choice. This is one of several situations in the XML family of standards where there is more than one way of doing the same thing, and no obvious way to choose between them. As the frequency of questions about the element-vs-attribute choice shows, this confuses users no end; it also complicates software tools. MK xml-dev: A list for W3C XML Developers.
