i believe this strategy would be incompatible with optional
semantic arguments. for example, the ERG treats quite
a few verbs as optionally transitive, e.g.
(1) He exaggerated.
(2) He exaggerated the problem.
both use the same predicate _exaggerate_v_1. i would
think one should be able to generate (1) from either of
the following inputs
_exaggerate_v_1[ARG0 e, ARG1 x]
_exaggerate_v_1[ARG0 e, ARG1 x, ARG2 u]

this strategy would mean that argument positions cannot
be underspecified in generator inputs. i think one might
well want to be able to generate from something like:

i believe there is no running away from a post-generation
semantic compatibility test, e.g. MRS subsumption, so as
to deal with various types of underspecification in inputs
to the generator.
