Seems real clean to me. -Tim To piggy back on what Tim says, I think the idea of having PIs in the document point to a catalog and/or resource directory--or otherwise having the catalog/RD embedded in the document--doesn't seem like the modern (or best) way to do things. Again, I think this gets close to other issues that were discussed under XML Packaging in the past [1],[2] (which is part of why XML Packaging never happened--it encompassed too many related but distinct issues--lets try to avoid doing that in our current resource directory work). Associating one resource with another one is probably better done using some packaging/association method--be that a manifest, multipart mime, RDF, etc.--than by insisting that the two resources are either combined in the same XML file or referenced directly from each other. If one needs some level of guarantee that a certain association is uncompromised, then use digital signatures [3] on the package/manifest/whatever. paul [1] http://www.w3.org/XML/2000/07/xpkg-19991207-min [2] http://www.w3.org/1999/07/xml-pkg234/Overview [3] http://www.w3.org/TR/xmldsig-core/
