Error checking type of the expression while using xalan

The idea is to select subset of labels with specific language code:

  <xsl:variable name="extLangCode" select="//Invoice/@languageId" />

  <xsl:include href="./labels.xsl" />

  <xsl:variable name="labelsXml">
    <xsl:call-template name="labels" />
  </xsl:variable>

  <xsl:variable name="labels" select="$labelsXml/labels/label[@lang=$extLangCode]" />

a part of labels.xsl:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:template name="labels">
        <labels>
            <label key="pageNr" lang="kl">Page</label>
            <label key="pageNr" lang="en">Page</label>

It throws:

[FATAL]: Error checking type of the expression 'FilterParentPath(variable-ref(labelsXml/result-tree), ParentLocationPath(step("child", 16), step("child", 18, pred(=(step("attribute", 17), variable-ref(extLangCode/node-set))))))'.

Xalan is an XSLT 1 processor, in XSLT 1 your variable is a result tree fragment and you can't apply XPath on result tree fragments without converting them first to node-sets so you need e.g. <xsl:variable name="labels" select="exsl:node-set($labelsXml)/labels/label[@lang=$extLangCode]" xmlns:exsl="http://exslt.org/common"/>.
