xslt extension method being called more times than expected

            </xsl:otherwise>

</xsl:template>

When I apply this xslt though, the acmex:DeriveValue extension method gets called 110 times, whereas I would expect it to be called 3 times. Not sure why?

Well <xsl:template match="node()|@*"> matches any node for which you don't have any more specific template. And then inside of that template you apply templates to all attributes and all child nodes and compute that parameter value calling the extension function. Maybe you want to use a global parameter or variable where you compute the values once.
