A variable cannot calculate data. You probably meant something else.

A variable cannot be called -- it is just referenced.

How do you know that? This is the first time somebody mentions that an
XSLT processor will re-evaluate a global xsl:variable every time it's
being referenced. Could some of the XSLT processors developers say if
this is meaningful at all?

In case the xsl:variable is really declared globally (it is a child of
the xsl:stylesheet element), then there's no reason why it should be
continuously re-evaluated.

If what you describe is true, it sounds extremely strange. Probably you
didn't describe the problem precisely enough? Which XSLT processor are
you using?
