I had something like this in mind:

  <p:pipeline>
    ...

    <p:pipeline name="somecommonsteps">
      ...
    </p:pipeline>

    <p:choose>
      <p:when>
        <p:step kind="somecommonsteps">
         ...
        </p:step>
        <p:step kind="postproc"/>
      </p:when>
      <p:otherwise>
        <p:step kind="somecommonsteps">
         ...
        </p:step>
      </p:otherwise>
    </p:choose>

True. But requiring all pipelines to be in external files strikes me
as analagous to requiring all xsl:templates to be in separate files.

                                        Be seeing you,
