The same reason SOAP was invented, I'd imagine - because in order to
justify charging your customers an arm and a leg for a solution, you
have to convince them that you're doing something new and valuable,
even when you aren't.

As Tim said, WAP doesn't matter any more.  WAP 2 specifies (last time I
checked) that TCP + HTTP + XHTML-Basic is a conformant stack.  Not that
we needed them to tell us that, but it's nice to see them acknowledge
their own demise. 8-)
