Subject: Creating HTML and XHTML with one stylesheet with namespace-alias

Can someone please confirm if what I'm doing here conforms to the XSLT
1.0 spec?  It seems to crash Xalan-J 2.7.0, but Saxon 6 and MSXML 4 do
what I want.  (XSLT 2.0 clearly states that this works, and indeed Saxon
8 does so.)

I am using a large stylesheet, call it foo2html.xsl, which generates
HTML 4 (un-namespaced, as HTML should be) using literal result elements:
  <!-- Lots of templates like this. -->
  <xsl:template match="/foo">
    <html>
      <xsl:apply-templates/>
    </html>
  </xsl:template>

I want to use that same stylesheet to generate equivalent,
properly-namespaced, XHTML 1.0, by importing it into a "shell"
stylesheet that maps the null namespace to the XHTML namespace.  I use
xsl:namespace-alias to map the default namespace prefix, in this case no
namespace, to the XHTML namespace.

<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:xhtml="http://www.w3.org/1999/xhtml/">
  <xsl:import href="foo2html.xsl"/>
  <xsl:output method="xml" doctype-system=
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
    doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" />
  <xsl:namespace-alias
    stylesheet-prefix="#default"
    result-prefix="xhtml"/>
</xsl:stylesheet>

I'm not fussy about whether the output makes use of default namespaces
or not, provided that it's valid XHTML.  I would prefer to do the
transform in one pass.

Specifically, what I want to know is:
Is is allowed for namespace-alias to map the null namespace in XSLT 1.0?

Thanks.
