The pipeline

<p:declare-step xmlns:ex="http://example.com/sample"
                xmlns:p="http://www.w3.org/ns/xproc"
                xmlns:t="http://xproc.org/ns/testsuite/3.0"
                xmlns:xs="http://www.w3.org/2001/XMLSchema" version="3.0">
   <p:output port="result"/>
   <p:input port="source"/>
   <p:variable name="gi" select="xs:QName('ex:p')"/>
   <p:viewport match="*[node-name(.) = $gi]">
      <p:add-attribute attribute-name="v"
                       attribute-value="true" match="/*"/>
   </p:viewport>
