/ Alessandro Vernet <avernet@orbeon.com> was heard to say:
| We can try to define precisely what "evaluate" means, like Alex did.
| Alternatively, I think that we can clarify this by just saying that a

Yes. I like that. Any unconnected output is implicitly connected to
bit-bucket:

  <p:declare-step type="p:dev-null">
    <p:input name="source" sequence="yes"/>
  </p:declare-step>

In fact, my impl literally does this at the moment. (Except that
bit-bucket is in my extension namespace.)

                                        Be seeing you,
                                          norm
