I've never heard of tunneling, but it worked. Thanks! I think the hard part about learning XSLT is not knowing what terms to google when searching for a solution, especially for the more complex concepts. There are plenty of good references available if you know what you want. Personally, I find the spec very hard to use as a reference document. Thanks, again!

Couldn't you address this by processing not the element to which your XPath points, but its closest data-value ancestor, as in <xsl:variable name="amt-source" select="$node/sax:evaluate(substring-after($field, concat($rows,'/')))/ancestor::data-value[1]" mode="display"/> and then <xsl:apply-template select="$amt-source"> <xsl:with params ... /><!-- passing in your precision, etc. --> </xsl:apply-templates> <xsl:template match="xpath" mode="display"> <xsl:param name="precision" .../> <xsl:value-of select="fc:nbr-format(number(.),$precision,'true','$')" /> </xsl:template> ... with more templates to match your formatting markup? You might want to use the XSLT 2.0 tunneling parameters feature, if you can. Otherwise just make sure that any templates in the "display" mode pass the parameter(s) correctly. I hope that's somewhat on track, or at least sparks your thinking.
