Unfortunately, my experience with libxslt is quite similar to that of David
Tolpin.

The latest problem was using this stylesheet:

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

  <xsl:output method="text"/>

 <xsl:key name="kdistNS" match="namespace" use="."/>

  <xsl:template match="/">
    <xsl:variable name="vrtfNamespaces">
      <xsl:apply-templates select="*">
        <xsl:with-param name="pNamespaces" select="/.."/>
      </xsl:apply-templates>
   </xsl:variable>

   <xsl:for-each
   select="ext:node-set($vrtfNamespaces)/*
                  [generate-id()
                  =
                   generate-id(key('kdistNS', .)[1])
                   ]">
     <xsl:value-of
      select="concat('&#xA;', substring-before(.,'|'),
                     ': ', substring-after(.,'|')
                     )"/>
   </xsl:for-each>
  </xsl:template>

  <xsl:template match="*">
    <xsl:for-each select=" namespace::*">
      <namespace>
        <xsl:value-of select="concat(name(), '|', .)"/>
      </namespace>
    </xsl:for-each>

    <xsl:apply-templates select="*"/>
  </xsl:template>
</xsl:stylesheet>

to transform this source xml document:

<test1>
  <foo:test xmlns:foo="bigrabbit" foo:gg="3"
            foo:hh="4">
    <bar xmlns:foo="littlerabbit"
         foo:squid="fish"/>
    <baz xmlns:hi="anothernamespace"
         hi:attr="value" />
  </foo:test>
  <p1:anc1 xmlns:p1="ns1">
    <p1:anc2 xmlns:p1="ns2">
      <p1:anc3 xmlns:p1="ns1" />
    </p1:anc2>
  </p1:anc1>
</test1>

As result I do not get any output from the transformation, but only these
messages:

Transformation failed.

I am aware of the fact that the versions I have of libxml/libxslt are
probably not the latest one available and I hope that this transformation
runs OK with the newest versions.

The result from MSXML3 (with MS native implementation of the node-set()
extension), MSXML4,  dotNet XslTransform(), Saxon 6.5.3, JD, XalanJ 2.4.1
and 4xslt is:

xml: http://www.w3.org/XML/1998/namespace

foo: littlerabbit
hi: anothernamespace
p1: ns1
p1: ns2
