Try whether
  <xsl:stylesheet
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
    xmlns:fn="http://www.w3.org/2005/xpath-functions";
    version="1.0">

  ...


	  <xsl:choose>
		<xsl:when test="function-available('str:split')">
		  <xsl:copy-of select="str:split('a b c', ' ')[1]"/>
		</xsl:when>
		<xsl:when test="function-available('fn:tokenize')">
		  <xsl:copy-of select="fn:tokenize('a b c', ' ')[1]"/>
		</xsl:when>

works with Xalan.
