Is the following library conformant?

Consider:

<p:library xmlns:p="http://www.w3.org/ns/xproc" version="1.0"
           xmlns:test="http://xproc.org/ns/testsuite/test">

<p:declare-step type="test:step" name="test-step">
 <p:input port="source" sequence="true"/>
 <p:output port="result"/>
 <test:step4/>
</p:declare-step>

<p:declare-step type="test:step4" name="test-step">
  <p:input port="source" sequence="true"/>
  <p:output port="result"/>
  <test:step/>
</p:declare-step>

</p:library>

Is that library valid?

                                        Be seeing you,
                                          norm
