I'm not clear on the difficult part. Looking up IDs is trivial. Traversing an IDREF is just a matter of looking up an ID so that's trivial too. Setting an ID is just setting an attribute so that's trivial too. Of course the underlying implementation needs to know that the attribute is an ID attribute but that's not particularly difficult either. Being able to change the DTD to make an attribute INTO an ID attribute would be neat, but I think that that is a clearly separable problem: a DTD problem instead of a document instance problem.
