Transformation with XSLTProcessor

Hi,
I try to do the following:

-- file.xml --
<?xml version="1.0" encoding="ISO-8859-1" ?>
<catalog>
  <cd>
    <artist>Bob Dylan</artist>
    <country>USA</country>
    <artist>Heino</artist>
    <country>Germany</country>
  </cd>
</catalog>

-- 1.xsl --
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/
Transform">
  <xsl:include href="2.xsl"/>
</xsl:stylesheet>

-- 2.xsl --
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
  <h2>CD</h2>
  <ul>
    <xsl:for-each select="catalog/cd">
      <xsl:sort select="artist" order="ascending" />
        <li><xsl:value-of select="artist"/> - <xsl:value-of
select="country"/> </li>
    </xsl:for-each>
  </ul>
</xsl:template>
</xsl:stylesheet>

-- anotherfile.html --
...
//for mozilla/netscape
processor = new XSLTProcessor();
xslt = document.implementation.createDocument("", "", null);
xslt.async = false;
xslt.load(xslURI);
processor.importStylesheet(xslt);

src_doc = document.implementation.createDocument("","", null);
src_doc.async = false;
src_doc.load(xmlURI);

result = processor.transformToDocument(src_doc);
xmls = new XMLSerializer();
output = xmls.serializeToString(result);
...

If the imported stylesheet (in this case 1.xsl) has an include or
import tag, the transformation fails. Is there a way to include more
than one xsl file?
