I was talking about testing over pipeline parameters without having to 
test xpaths against documents. Example:

<p:pipeline>
   <p:param name="debug" value="false" />

   <p:step name="xslt">
     ...
   </p:step>
   <p:if test="true($debug)">
     <!-- perform some debugging tasks -->
   </p:if>
   ...
</p:pipeline>


If this type of features isn't allowed in the pipeline language, we 
would have to define the debug flag in a dummy document and afterwards 
test that document with a xpath expression.

Cheers,
Rui
