Looking just at the examples, you're using what amount to namespace prefixes in attribute values without declaring what namespaces those prefixes bind to. For example: <request> <query> <equals> <property name="dc:title"/> <string caseSensitive="true">The Ugly Duckling</string> </equals> </query> </request> While it's clear to me (a human) that you mean Dublin Core's "title" property, it's not explicit. This should be explicitly listed as: <request xmlns:dc="http://purl.org/dc/elements/1.1/";> <query> <equals> <property name="dc:title"/> <string caseSensitive="true">The Ugly Duckling</string> </equals> </query> </request> Of course, since "dc:title" is an attribute value, rather than a tag name, XML parsers won't do anything with it, so the specification will have to mention explicitly that the name attribute of property must be interpreted using the namespace prefixes that are in scope. W3C has set a precedent for doing this with XSLT. I would also recommend giving the entire XML dialect an XML namespace.
Yes, I absolutely agree on everything you said :-) I left xml namespacing out to clarify the examples. The naming of the metadata fields have not been settled upon yet, so these are pretty bogus actually :-) Cheers, Mikkel
