RE: Implicit parameter input on p:pipeline

Just one more question: Is the following alowed?

<p:pipeline type="mypipeline">
  <p:input port="parameters" kind="parameter"/>
  <p:output port="parameters-out">
    <p:pipe step="mypipeline" port="parameters"/>
  </p:output>
</p:pipeline>

Or:

<p:pipeline type="mypipeline">
  <p:input port="parameters" kind="parameter"/>
  <p:identity>
    <p:input port="source">
      <p:pipe step="mypipeline" port="parameters"/>
    </p:pipe>
  </p:output>
</p:pipeline>

In other words, can a non-parameter input/output port contain a pipe
binding to a parameter input port? I guess this is not allowed, because
otherwise there would be no need for the p:parameters step. But does the
specification mention this somehere?

Vojtech
