[xsl] How many passes through the document

[Ihe Onwuka <ihe.onwuka@xxxxxxxxxxxxxx>]

Will the stylesheet below result in 2 passes through the document. I
the normal recursive descent parsing and 2 to evaluate the global
variable?

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xs="http://www.w3.org/2001/XMLSchema";
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                version="2.0"
                exclude-result-prefixes="xs">

   <!-- I type is irrelevant for this example -->
   <xsl:variable name="all">
      <xsl:apply-templates select="*"/>
   </xsl:variable>

   <xsl:template match="/">
      <xsl:value-of select="sum(key('counts',max($all))/count(@*))"/>
   </xsl:template>

   <xsl:template match="*">
      stuff
   </xsl:template>

   <xsl:template match="text()"/>


</xsl:stylesheet>
