You missed my point: a meta language is a language used to describe other languages. As such, it is itself a language. Human languages, computer languages, foreign languages, and meta languages are all kinds of language, by definition. Certainly, the DTD subset of XML is a meta language and is therefore a language. Without DTDs, I think it would indeed be difficult to argue that XML is a language (or, for that matter, a meta language). It's then more of an alphabet, a set of symbols from which languages can be constructed. We are way off topic, and this kind of meta-meta discussion is far better held on xml-dev, where people are used to deleting such threads...
