RE: [xsl] Namespaces: part II

["Michael Kay" <mike@xxxxxxxxxxxx>]

You can do something like this:

<xsl:template match="text">
  <xsl:element name="xsl:value-of">
    <xsl:copy-of select="namespace::*"/>
    <xsl:copy-of select="@select"/>
  </xsl:element>
</xsl:template>

This will copy all the inscope namespaces from the source <text> element to
the constructed <xsl:value-of> element.
