Global variables and recursive calls

[Kevin Malone]

Is it possible to update a global variable passed via a parameter in
'call-template' that is recursive, or does that create a circular reference?
I seem to be able to update only a local variable with the same name but may
not have the syntax right.

You can't "update" a variable at all. Once a value was assigned, it's
read-only.

It's not clear to me what you mean, but this allows you to call a template
recursively while preserving the value of the parameter `parm-name':

<xsl:call-template name='template-name'>
<xsl:with-param name='parm-name' select='$parm-name'/>
</xsl:call-template>

It will work whether the parameter is defined in the template or at
the style sheet level, but the parameter must be in scope.

You may want to ask your question again, including a short example of
what you're trying to do.
