It's trickier in XProc because sequence matters more so than in XSLT.

You can put anything you want in p:pipeinfo and you can put that
anywhere you want.

Sure, you can do that.

  <p:declare-step type="px:my-extension"
		  px:class="org.xproc.extensions.MyExtension">
    <p:input port="source"/>
    <p:output port="result"/>
  </p:declare-step>
