Actually, he has. I believe his reasons are that he knows he can get the job that he thinks needs doing done that way. It's a known technology, while other technologies would require a substantial learning curve.' I can't say I disagree, either.

Well, I've been posting my thoughts on the matter in XML a few times, and so far the only significant responses have been from the person with a commercial product that uses XML. (Pretty good product, too.) Every time I go around on it, I find a bit more clarification.

Yup.

Astrologers? Money? I don't think these two words belong in the same sentence.
