Predicates are allowed as filters on a node test, not standalone as the 
above shows.

But predicates aren't what you need ... you can just write an expression 
that uses the value of the child and compares it to a string.  The value is 
a string already, so no conversions are required.

An example is below ... I hope this helps.

T:\FTEMP>type test.xml
<?xml version="1.0"?>
<test>
 <person><sex>M</sex><name>John</name></person>
 <person><sex>F</sex><name>Jane</name></person>
</test>
T:\FTEMP>type test.xsl
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/XSL/Transform/1.0";>

<xsl:template match="/test">
  <xsl:for-each select="person">
    <xsl:choose>
      <xsl:when test="sex='M'">&#xa;Male: </xsl:when>
      <xsl:when test="sex='F'">&#xa;Female: </xsl:when>
      <xsl:otherwise>&#xa;Who knows?: </xsl:otherwise>
    </xsl:choose>
    <xsl:value-of select="name"/>
  </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

T:\FTEMP>call xsl test.xml test.xsl test.txt
T:\FTEMP>type test.txt

Male: John
Female: Jane
T:\FTEMP>
