Change the above to

  <xsl:variable name="webs" select="count(WebExtra)"/>
  <xsl:choose>
    <xsl:when test="$webs &gt; 3">

I.e. instead of trying to compare a document node to a string, compare a
number to a number. (In XPath 1.0 the variable was bound to a Result Tree
Fragment and for comparison it was first converted to a string and then to a
number.)
Cheers,

Jarno
