I think Peter is, to some extent just using ad hoc combinations of DTD fragments. The important laws are written. By the time you make the decision XML, XLL, CML, RDF with HTML element types for general text, the DTD has almost written itself. That it is not explicit is not of so great interest, in that the fragments are explicitly defined and available. The absense of an explicit DTD for them suggests that there are no additional constraints to be imposed on them, and that the fragments can be compbined as freely as possible. I think the future of XML DTD production will largely just be in this recombining existing DTD fragments ("element type sets" or "microdocument DTDs" or "little languages" or even "architectures") in various ad hoc ways.
