Thanks for your helpful suggestions. With Saxon and MSXML (with its
own node-set extension function), things work fine. But with Xalan-J,
the namespaces are not being output. It seems this could be a bug with
Xalan.. Probably somebody could comment on this.

Hi Mukul,

You need the node-set extension I think.
Change your template that matches elements like below:

<xsl:template match="*">
    <xsl:element name="{translate(name(), $small, $caps)}"
      namespace="{translate(namespace-uri(), $small, $caps)}">
      <xsl:variable name="currentNamepsace" select="namespace-uri()"/>
      <xsl:variable name="nsHolder">
and not(name()='xml')]"
            <xsl:attribute name="{translate(name(), $small,
              namespace="{translate(., $small, $caps)}"></xsl:attribute>

      <xsl:copy-of select="exslt:node-set($nsHolder)/test/namespace::*"/>
      <xsl:apply-templates select="@*"/>

and add
on the stylesheet element.

Basically you need to create new namespace nodes and copy them instead
of the old namespaces and also you need to change the namespace of the
created elements and attributes (so you have to change accordingly the
template that handles your attributes).
