I'd like it, but don't think that RDDL can be assimilated to a doctype since it's describing a namespace and that several namespaces can be used in a XML document. I don't think either that the RDDL document associated with the namespace of the document element since that would miss the point that inovative users may add foreign namespaces in a fashion that was not envisioned by the designer of this namespace. I think that we truly miss the notion of a "DocType" describing the specific mixture of namespaces of the current document and eventually giving hints on processing and validation models. This could be done using documents with the same syntax than RDDL, but a mechanism would need to be added to associate this "pseudo RDDL doctype" to an instance document and I don't think that we can rely on the actual namespace URIs found in a document since they identify pieces of the document rather than the document as a whole.
