Number of times apply-templates gets executed.

Hi,

I am new to XSL and I have several questions - some of them might be really
easy ones but I just want to confirm.
1. I believe its not possible to change the value of <xsl:variable> once its
set - correct?

2. Is there a way to figure out how many times a template was applied when
using <xsl:apply-templates>?

3. Is there an easy to implement a counter or a boolean in xsl? If yes then
how? Implementing either one would be fine.

Thanks
V. Patel.
