EXSLT 'function' error

[drkm <da...@yahoo.fr>]

  Hi

  I have a trouble with the following XSLT script:

    <?xml version="1.0"?>

    <xsl:stylesheet
        version="1.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:func="http://exslt.org/functions"
        xmlns:my="..."
        extension-element-prefixes="my func">

      <func:function name="my:nil">
        <xsl:param name="attr"/>
        <func:result select="not($attr) or ($attr/@xsi:nil='true')"/>
      </func:function>

      <xsl:template match="/">
        <xsl:message>
          <xsl:text>root: </xsl:text>
          <xsl:value-of select="my:nil(root)"/>
          <xsl:text>&#10;elem: </xsl:text>
          <xsl:value-of select="my:nil(root/elem)"/>
        </xsl:message>
      </xsl:template>

    </xsl:stylesheet>

  With the following XML document:

    <root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <elem xsi:nil="true"/>
    </root>

the expected results are first 'false' and second 'true'.  But they are
both 'false'.  If I directly use the XPath expression from the
'func:function' in the 'xsl:value-of', all is ok.  It is ok also if I
use:

    "($attr/@xsi:nil='true') or not($attr)"

in place of:

    "not($attr) or ($attr/@xsi:nil='true')"

  Tested with Xalan 2.4.1 and 2.7.0.

  Thanks,

--drkm
