[xslt] Bug in import with namespaces?

[Brent Hendricks <brentmh ece rice edu>]

Hello,

I'm experiencing what I think is a bug in how namespaces are handled
with imported stylesheets

For example using the following text file:

<?xml version= "1.0"?>
<document xmlns="http://my/namespace";>
  <item>Success</item>
</document>

Given an outer stylesheet:

<?xml version= "1.0"?>
                            
<xsl:stylesheet version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

  <xsl:import href="inner.xsl"/>

  <!-- Root Node -->
  <xsl:template match="/">
    <xsl:apply-templates/>
  </xsl:template>
  
</xsl:stylesheet>

that imports an inner stylesheet:

<?xml version= "1.0"?>

<xsl:stylesheet version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns:my="http://my/namespace";
  exclude-result-prefixes="my">

  <xsl:template match="my:document">
    Big <xsl:apply-templates select="my:item"/>
  </xsl:template>
  
</xsl:stylesheet>


The template for matching my:document seems to work just fine, but
it's having problems with the select="my:item".  the current cvs
version of libxslt spits out

Error xpath.c:6570: Undefined namespace prefix
xmlXPathEval: evaluation failed

Looking at xpath.c it appears that the call to xmlXPathNsLookup() is
drawing a blank here.  Poking around in gdb, it looks like the
namespace is defined in the array ctxt->namespaces, but it doesn't
show up in the hash table ctxt->nsHash.  I tried to dig back through
the source code, but I got a bit lost :)
