Proposed component: p:count

<p:declare-step type="p:count">
  <p:input port="source" sequence="yes"/>
  <p:output port="result" sequence="no"/>
</p:declare-step>

p:count returns <c:result>#</c:result> where "#" is the number
of documents that were in the input sequence.

                                        Be seeing you,
                                          norm
