Lout uses magic string "??" for unresolved xrefs, so you can @Case on
it like this

    def @InSection
      left  @DefaultText
      right @SectionNumber
    {
      @SectionNumber @Case {
        "??" @Yield @DefaultText
        else @Yield { in section @SectionNumber }
      }
    }


And in your document:

    ... discussed { elsewhere } @InSection @NumberOf {some.section.tag}.


Of cause, you will still get "unresolved cross reference" messages.


Hope it helps.
