For those on ietf-xml-mime and not on ietf-types, my original message can be found here; http://eikenes.alvestrand.no/pipermail/ietf-types/2005-June/000817.html > I think that you have presented some requirements which are not > addressed by any of the existing mechanisms. > > > But I believe the security problem is just one manifestation of the > > layering problem inherrent in using intrinsic dispatch (of which XML > > namespace dispatch in one kind); that an extrinsic dispatch mechanism, > > like media types, cleanly separates the "what" - the raw data - from > > the "how" - the semantics with which that data is to be interpreted. > > I do not think that media types are good enough for multi-namespace > documents and that W3C should develop something different. I think media types are fine for multi-namespace documents. I just think that XML, by itself, doesn't provide a sufficiently rich framework to address the root cause of the need for an explosion of media types with these documents. Consider RDF/XML documents, almost all of which are comprised of data from several independent namespaces. Yet a single media type, application/rdf+xml, suffices for (almost[1]) all RDF/XML documents. >Although > your example can be addressed by specialized media types, my example > (schemas embedded within XHTML are referenced by XPointer) cannot. Can you elaborate on that example please? I don't think I've seen any schemas embedded in XHTML before. Cheers, [1] http://esw.w3.org/topic/RdfAndMediaTypes Mark. -- Mark Baker.
