Re: Head

Also:

<p:declare-step type="p:head">
  <p:input port="source" sequence="yes"/>
  <p:output port="result" sequence="yes"/>
  <p:option name="count" required="yes" value="1"/>
</p:declare-step>

You can either say count is required or you can say it has the default
value 1, you can't say both. I suggest making it required.

                                        Be seeing you,
                                          norm
