You don't necessarily need to recalculate. As in any other  functional
programming language, you don't have global variables (nasty things
anyway) but you can pass information explictly as arguments to

In the case of xsl this means declaring your variable as a
in any template where it might be used, and explicitly passing on a
value via xsl:param in calls to xsl:apply-templates.
