[xsl] xhtml XPath problem

I am having trouble with XPath when trying to match elements in an xhtml document stored in an xsl:variable. I have no trouble when the xhtml is missing its DOCTYPE declaration, but can't match elements when the xhtml is conforming. I used xalan for this example:

test.html:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.or
g/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"; >
<head>
<title>test doc</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
</head><body></body>
</html>


test.xsl:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:my="http://lib.virginia.edu/my-template-language";>
  <xsl:variable name="source" select="/" />
  <xsl:template match="/">
    <xsl:value-of select="$source/html/head/title" />
  </xsl:template>
</xsl:stylesheet>

Result:

<?xml version="1.0" encoding="UTF-8"?>

I would like to see the title "test doc" there but it is not. If I modify my test.html file it works:

test.html:

<html><head>
<title>test doc</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
</head><body></body>
</html>


Result:

<?xml version="1.0" encoding="UTF-8"?>
test doc

Can anyone let me know why this is not working with a valid xhtml document?
Thanks in advance for any help,
