maybe really a question for xsl-list rather than om-list, but since you
ask,

==============mk.xml
<OMA>
  <OMS cd="cartesian-products" name="pair"/>
  <OMV name="a"/>
  <OMV name="b"/>
</OMA>

==============mk.xsl
<xsl:stylesheet 
  xmlns:xsl="http://www.w3.org/XSL/Transform/1.0">


<xsl:template match="OMA[OMS[
      position()=1 and 
      @name='pair' and 
      @cd='cartesian-products']]">
  (<xsl:apply-templates select="*[2]"/>,<xsl:apply-templates select="*[3]"/>)
</xsl:template>


<xsl:template match="OMV">
 <xsl:value-of select="@name"/>
</xsl:template>


</xsl:stylesheet>

=================

xt mk.xml mk.xsl 

  (a,b)
