I don't have XalanJ 2.5.1

The transformation below works without any problem when run with XalanJ
2.4.1, Saxon 6.5.3, MSXML3, etc.

If it produces an error with XalanJ 2.5.1 then this may be a bug  with this
XSLT processor or otherwise all other XSLT processors are non-compliant:

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

 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <my:elNames>
   <name>id</name>
 </my:elNames>

 <xsl:variable name="elNames"
      select="document('')/*/my:elNames/name"/>

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*">
    <xsl:choose>
      <xsl:when test="not(name() = $elNames)">
        <xsl:copy>
          <xsl:copy-of select="@*"/>
          <xsl:apply-templates select="*[name() = $elNames]"/>
          <xsl:apply-templates/>
        </xsl:copy>
      </xsl:when>
      <xsl:otherwise>
        <xsl:attribute name="{name()}">
          <xsl:value-of select="."/>
        </xsl:attribute>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

  <xsl:template match="value">
    <xsl:value-of select="."/>
  </xsl:template>
</xsl:stylesheet>

when applied on this source.xml:

<customerList>
  <customer>
    <field>
      <id>customerId</id>
      <value>cust1</value>
    </field>
    <field>
      <id>customerName</id>
      <value>Customer  1</value>
    </field>
    <fieldGroup>
      <id>homeAddress</id>
      <fieldList>
        <field>
          <id>street</id>
          <value>98th  Street </value>
        </field>
        <field>
          <id>city</id>
          <value>Chicago</value>
        </field>
      </fieldList>
    </fieldGroup>
    <fieldGroup>
      <id>companyAddress</id>
      <fieldList>
        <field>
          <id>street</id>
          <value>128th  Street</value>
        </field>
        <field>
          <id>city</id>
          <value>Chicago</value>
        </field>
      </fieldList>
    </fieldGroup>
  </customer>
</customerList>

the wanted result is produced:

<customerList>
  <customer>
    <field id="customerId">cust1</field>
    <field id="customerName">Customer  1</field>
    <fieldGroup id="homeAddress">
      <fieldList>
        <field id="street">98th  Street </field>
        <field id="city">Chicago</field>
      </fieldList>
    </fieldGroup>
    <fieldGroup id="companyAddress">
      <fieldList>
        <field id="street">128th  Street</field>
        <field id="city">Chicago</field>
      </fieldList>
    </fieldGroup>
  </customer>
</customerList>


So, is issuing an error message by XalanJ 2.5.1 a bug?
