Failure to copy namespace nodes from RTF

[Michael Ludwig]

Xalan-J 2.7.1 fails to copy the namespace nodes from an RTF.
Maybe this is a known issue. If so, my apologies.

Saxon 6.5 and 9.1 as well as LibXSLT 1.1.24 produce namespace
declarations as expected.

Input:
------
<Tomate/>

XSL:

  <xsl:output indent="yes"/>

  <xsl:variable name="ns-rtf">
    <u:Urmel xmlns:u="http://urmel.de"/>
    <g:Gurke xmlns:g="http://gurke.de"/>
  </xsl:variable>

  <xsl:template match="/*">

      <xsl:copy-of select="exsl:node-set( $ns-rtf)//*/namespace::node()"/>
      <xsl:copy-of select="node()"/>

  <u:Test/>
  <g:Test/>
</Tomate>
