I'm using the XSLT scripts in MATLAB. That mean Saxon on XSLT 1.0.

I guess what you said about the nodeset extension means I should made my 
code something like this:

 <xsl:variable name="DEVICE_TYPE_FLAGS">
  <xsl:choose>
   <xsl:when test="$APP_MODEL = 2812">
    <IS_ICD>true</IS_ICD>
    <IS_ATRIAL_ICD>true</IS_ATRIAL_ICD>
   </xsl:when>
   <xsl:otherwise>
    <IS_ICD>true</IS_ICD>
    <IS_ATRIAL_ICD>false</IS_ATRIAL_ICD>
   </xsl:otherwise>
  </xsl:choose>
 </xsl:variable>

But I'm still stuck with strings in the text node of tags like <IS_ICD>. Is 
there a way that I can make the contents inside a tag boolean?

Thanks.

Cheers,
Hoi
