                exclude-inline-prefixes="#all">
   <p:option name="opt" as="xs:string?"
             select="'outer-default'"/>
   <p:output port="result"/>
   <p:declare-step type="s:inner-step">
      <p:option name="opt" as="xs:string?"
                select="'inner-default'"/>
      <p:output port="result"/>
      <p:identity>
