Thanks for the response.

Let me explain ...

I need this as a "test driver". I have an application that processes
XML documents (LOTS !!!!). To evaluate my app. I need LOTS-and-LOTS
of XML-documents - more than I ever want to store on my system.

Obviously, this is not what a DTD was intended for. The way I imagine
it to work is {<specification>, DTD} -> xml-docs.

The spec. would probabilistically describe what I expect on average
the resulting XML-doc. to look like.

Just hoped somebody had already implemented that.

I'll check out the functions you pointed out.

Thanks,

Arno
