CR 2.0 Change METS ID attributes to be of type xml:id

Move to xml:id? Since ID presumes access to the DTD (for awareness that it is an XML ID type), and since METS has no requirement (and I believe should have no requirement) to parse the DTD, might METS change to xml:id in a new version instead? (as did TEI in moving to P5). Of course most consuming apps would be aware of the application's syntax, but I think it might be more robust to use xml:id (TEI also made such a change in going to P5).
