Are there three XHTML "vocabularies" or just three DTDs? We could just think of them as ONE language with ONE processing model that happens to have three different DTDs depending on how picky you (either author or recipient) want to be. >... > to which one might have a choice of resolving to DTD, XML Schema, > RELAX NG, etc. all of which define the document model in question. I think that the three different DTDs are like the difference between an XML Schema and a RELAX NG. They may check different things in slightly different ways but the *processing model* is the same and that's what's most important. Paul Prescod
