I was expecting too much from the grammar alone but my point still is a language with out the tools to interpret it is not very useful. Take writing an XSL processor as an example, does being able to parse an XSL document into a DOM tree help you with writing an XSL processor? I don't think it does.

I think it has a lot to do with the complexity of the language. With Joshua's example of a Lisp program I can certainly see how a DTD constrained editor would be fine. However, if someone gave me the DTD for Java and said I can use Xeena or JBuilder I would choose JBuilder. I wouldn't even want to imagine what writing C++ would be like under Xeena!
