Try telling someone who has rowed the Atlantic and is within sight of
land, that you think they could finish faster if they started again and
headed for a different destination. You would get roughly the same
reaction.

2.0? Who is pushing those arguments?
The arguments have been frequently rehearsed. For people who are using
XML Schema, it seems very natural indeed that the stylesheet should take
advantage of the type information that is thereby available. For
example, if you have 23 elements with the same type, being able to match
on the type is a real convenience. And there are many people who ARE
using XML Schema.
Don't ever imagine that everyone on the XQuery group wants strong typing
and everyone on the XSL group doesn't. That's a complete fallacy. Both
groups feel that they are now close to achieving the goals that they set
out to achieve.
