count of how many times a particular template is being called

Can I get a count of how many times a particular
template is being called?

Im thinking of something like - 

<xsl:variable name="globalVar" select"1" />

<xsl:template match="Node1">
        <xsl:for-each select="$Values">
                <xsl:call-template name="T1"/>                  
        </xsl:for-each>
</xsl:template>

<xsl:template name="T1">
        <xsl:if test="ValueIsValid">
                <xsl:call-template name="T2"/>
        </xsl:if>
</xsl:template>

<xsl:template match="T2">
        Called for <xsl:value-of select="$globalVar" />
        <!-- Increament the var???? -->
</xsl:template>

The final template creates the output.
I showed this for what I want. I know we cannot
reassign variables
in xsl. As I am iterating over $Values, that is a
variable, I am getting
undesired result by using xsl:number or position().
Can anyone give any hints?

Thanks
