that's a workaround not a signal.  so, if there's a secure path from a 
trust anchor to the qname AND if the stub is validating THEN this has
the same effect as DMNF.

however, for unsecured names or nonvalidating stubs, i'd like an
explicit signal.  thus, DMNF.  so far david conrad thinks a short i-d
could be worthwhile, so that's two (me and him).  anybody else?
