[xsl] counting the number of time i call a template

[Floch "Jean-Sébastien" <jsfloch at yahoo dot com>]

Hi all.
My problem is that we can't modify global variables in
xsl. But i need that functionality.
I have to count the number of time i call a template
Some of you will say "you can use count select="//elt"
in the root template", but in real life, my xml is not
as simple, and i can't predict the number of element
elt, and even where they are located in my tree.
And i need to count the number of time i use my
template because i want it to have different actions
for different values.

Thanks in advance,
Jean-Sebastien
