Yes. I think I could live with that, but what happens in the following

<p:declare-step name="main" type="...">
  <p:input port='source'/>
  <p:input port='style'/>
  <p:output port='result'/>

    <p:input port='stylesheet'>
      <p:pipe step="main" port="style"/>

The p:xslt step has an unbound parameter input port. Is that an error,
or do we bind it to an empty document?
