Use the document() function to access the XHTML. Do an identity transformation
(like in the XSLT spec under 'Copying') on the XHTML, except when you
encounter a node that indicates something dynamically generated is supposed to
go 'here' -- process those nodes specially.

<html xmlns:special="foo">
  <head>
    <title>xhtml template</title>
  </head>
  <body>
    <h1>generic stuff</h1>
    <table width="100%" cellspacing="20">
      <tr>
        <td>
          <special:data/>
        </td>
        <td>more generic stuff</td>
      </tr>
    </table>
  </body>
</html>

---

<xsl:variable name="xhtml" select="document('foo.xhtml')"/>
<xsl:variable name="orig-xml" select="/"/>

<xsl:template match="/">
  <xsl:apply-templates select="$xhtml" mode="copy"/>
</xsl:template>

<!-- identity transform -->
<xsl:template match="node()|@*" mode="copy">
  <xsl:copy>
    <xsl:apply-templates mode="copy"/>
  </xsl:copy>
</xsl:template>

<!-- replaces <special:data/> with an HTML list -->
<xsl:template match="special:data" xmlns:special="foo">
  <ul>
    <xsl:for-each select="$orig-xml/some/nodes">
      <li><xsl:copy-of select="."/></li>
    </xsl:for-each>
  </ul>
</xsl:template>
