Ok, friends, I surrender! And it's true, I spoke as one with little
practical experience. What I was thinking was that, based on things I had
read, it seemed that there was lot of machinery - a lot of pieces that did
different things - and that both ends of the relationship had to understand
each other a lot more intimately than might be the case with xml. But I've
got to agree that the xml area has gotten very complex itself.
Thanks to all for setting me straight.
