Re: [xsl] Unable to select wanted nodes

Hi, Ken...

This is a good point.  I wasn't aware that this would throw an error
in 2.0, but for what it's worth, that might really be desired
behavior, anyway.  His model seems to be that the element in question
should only ever have one attribute.  I don't know if he's using any
kind of schema to enforce that, but if he isn't, then the error thrown
by the transform would essentially be a (admittedly clunky, likely
with a not-very-helpful error message) form of validation check.

In any case, it might be worth explaining the detail, for the archives.

I've been meaning to ask, what's the new course you mentioned working
on recently?

-Brandon :)
