  So your processor is bugged (if it is claiming to be an XSLT 2.0
processor, what I expect because you're using @version="2.0").

  BTW, your initial param declarations were:

    <xsl:param name="..."/>
    <xsl:param name="..."/>

  exists() will give you true here, because when xsl:param (or
xsl:variable) has neither @select or content, its value is the
zero-length string.

  If you can test for both empty sequence of zero-length string, use
just <xsl:if test="$param">.
