Re: 'apply-templates' on parameter of 'call-template'

Is it legitimate to invoke 'xsl:apply-templates' on a parameter passed to 'xsl:call-template'?

In other words, should the following fragment be expected to work:

        <xsl:template match="/">
           <xsl:call-template name="test">
              <xsl:with-param name="body">
                 <p>This is my body</p>
                 <matchable id="123"/>
              </xsl:with-param>

           </xsl:call-template>
        </xsl:template>

        <xsl:template name="test">
           <xsl:param name="body">no body</xsl:param>

The Xalan error ("can not convert #RTREEFRAG to a nodelist") hints that I'm trying to do something basically contrary to the spirit of XSL, or at least XSL 1.0.

What I'd like to do can be described as follows: use 'call-template' to 'surround' an arbitrary block of XML, _contained in the XSL stylesheet_, by additional XML content - and have templates applied to the contained block in the usual way.

  <xsl:stylesheet
        xmlns:myns="my-namespace"
        exclude-result-prefixes="myns"

  <myns:data1>
         <p>This is my body</p>
         <matchable id="123"/>
  </myns:data1>

  ...
     <xsl:with-param name="body" select="document('')/*/myns:data1/node()"/>

As to why I want to do this particularly horrible thing, put it down to someone else's questionable design decisions. If the nodes that I want to 'surround' were in the XML rather than the XSL, this would be trivial.
