I hate the idea of 2 'if's in a language.
IMHO that makes it even more complicated.
In the past it's been asked whether we should prefer our logic in the
XPath or in the XSLT, or if in either/both, how to strike the balance.
IIRC it was Dimitre who asked, and Mike gave a characteristically
thoughtful answer, but no reliable principle has emerged.
I think we'll be using our aesthetic sense -- what looks right,
assessing clarity and concision in the usual way -- until we have
enough experience to derive some rules of thumb.
In any case it's going to be fun to see what kind of programming
styles emerge in 2.0.
Cheers,
Wendell
