The main point of my suggestion was the nesting of some element within a 
port declaration in order to provide the binding for the port. I'm quite 
happy to change the name to something that gives less encouragement to 
the reader to think of pipes and steps separately.

One other possibility I thought of was <put>: something like

<step kind="xslt" name="transform">
   <put in="source" source="validated!result" />
   <put in="stylesheet" load="style.xsl" />
</step>

and

<group name="...">
   <input name="document">
     <put source="previous-step!result" />
   </input>
   <output name="result">
     <put source="inner-step!result" />
   </output>
   ...
</group>

Cheers,

Jeni
