Well, theres another way of looking at this. You could argue that a
full understanding of lexicalRep would have these two graphs each
extended-RDF-entailing the other:
John age "5" .
John age _:x.
_:x lexicalRep "5" .
as long as everyone agrees that "5" is universally recognizable as
being a lexical representation, even when it just occurs 'naked', as
in the first graph. Then the content of the second graph could be
conveyed by the first one.
