I understand your point (I think), but I'm going to disagree with it
a little bit. One of the virtues of tags is that you don't have to
be, or shouldn't have to be, a programmer to use them. The sections
of the spec that you cite require that I as a tag user make the leap
from seeing getRowCount() mentioned in the spec to figuring out that
${result.rowCount} can be used to get the same value.
Maybe that connection is mentioned somewhere, but if it is, I missed it.
Just a mention of this principle, if it is indeed a JSTL principle,
somewhere early in the spec would be helpful to many of its readers.

I understand that point, too. But the working group *is* asking for
comments on the spec. I'm making a comment, one that I hope is a constructive
one. Don't take it as a slam on the spec, which I view as light years
ahead of previous editions - just as beta2 is so much nicer to work with
than EA3.
Besides, the messages of this thread pretty much constitute the necessary
documentation.
