Viewing intermediate results

Hi,

I also have a question that bears on debugging, but debugging the 
pipeline not the XProc as such.

As you know, I have multiple passes in XSLT. Say, three:

<p:pipeline xmlns:p="http://www.w3.org/ns/xproc"
   version="1.0" name="triple-play">
   <p:xslt>
     <p:input port="stylesheet">
       <p:document href="transform1.xsl"/>
     </p:input>
   </p:xslt>
   <p:xslt>
     <p:input port="stylesheet">
       <p:document href="transform2.xsl"/>
     </p:input>
   </p:xslt>
   <p:xslt>
     <p:input port="stylesheet">
       <p:document href="transform3.xsl"/>
     </p:input>
   </p:xslt>
</p:pipeline>

I am guessing if I made this into p:declare-step, I could have ports 
to show me the intermediate results after each transformation.

But I don't always want to see them, only sometimes.

Currently I have achieved this using three different XProc instances, 
each importing the previous in a cascade, so if I want to see 
intermediate results, I run the appropriate XProc. But this is 
suboptimal for several reasons.

I have a couple of ideas for things to try, but maybe I'm better off 
just asking what the best methods are?

In effect I'd like to implement a "production" and a "debugging" 
mode, with options to show me any or all the intermediate results in 
addition to or instead of the final result.

Gratefully as always,
Wendell
