Hello public-xml-id, Following this thread http://lists.w3.org/Archives/Public/public-xml-id/2008Aug/thread.html which demonstrates that (since Relax-NG does not modify the infoset) xl:id should be declared as NCNAME in a RelaxNG schema, I was wondering whether Schematron could be used to check various aspects of IDness? In particular I was wondering if anyone had already done it :) SVG, which introduced xml:id to a language that already had @id of type ID, http://www.w3.org/TR/SVGMobile12/struct.html#Core.attrib tries to give guidance on document authoring and document processing in the case that both attributes are used in the same document http://www.w3.org/TR/SVGMobile12/struct.html#idAttrs Since these are co-constraints, it looks as if Schamatron could help in checking this: a) warn if an element has both @id and @xml:id with different values b) check ID uniqueness by first converting @id to @xml:id for any element that has @id and does not have @xml:id, then using an xml:id-aware processor Does this seem like a feasible approach? -- Chris Lilley mailto:chris@w3.org Technical Director, Interaction Domain W3C Graphics Activity Lead Co-Chair, W3C Hypertext CG
