You can write RNG schemas with wildcard names, but the extent to which you can handle unordered element content with fully wildcarded names is very limited. > 2. Would the AF NG be a way to get that done? AF NG basically does what AF does, but with an external configuration file rather than attributes defaulted in from the DTD. It can: statically map an element name to a different name; dynamically map an element name to a different name held in a specific attribute of that element; rewrite attribute names; rewrite tokens in attribute values; convert simple content into the value of an attribute; leave out child elements or replace them with their content; leave out character content; AFAIK the only other thing AF can do is turn an attribute value into character content, which IMHO is not necessary. > I've drafted such a thing using XML Schema for > the HumanML project.

I would have to see details, but I think using RNG for the base schema would make a lot of sense. -- John Cowan <jcowan@r...> http://www.reutershealth.com I amar prestar aen, han mathon ne nen, http://www.ccil.org/~cowan han mathon ne chae, a han noston ne 'wilith. --Galadriel, _LOTR:FOTR_
