Gotcha. All of our pipelines have multiple trax transformations, so that 
kinda kills my hopes of xsltc for now at least.

Its a very specific case, setting selected="selected" for selectbox options. 
I was doing a string comparison for each item, ie:

<xsl:transform match="page:item">
  <xsl:param name="value"/>

  <option value="{@value}">
    <xsl:if test="$value = @value"><xsl:attribute 
name="selected">selected</xsl:attribute></xsl:if>
    
    <xsl:apply-templates/>
  </option>
</xsl:transform>

Its probably a corner case, but for a page with 10-15 dropdowns it made a 
huge difference.

Thats what I followed also. It sounds like the class-naming is the current 
hiccup for me though. Thanks.
