Hmmm. I suppose I can accept OT as a model of competence, but my instinct
is to say "Nu ma intereseaza" (I don't care) because I prefer to think of
linguistic models as processing models. This requires a fair bit of
hubris, but I find a non-production model of linguistics to be
rather pointless. It may suffice for an interim stage, but I
wouldn't want to waste a lot of research on what I think of as
a dead end.
And I still don't see what (aside from academic jealousy) prevents the
formation of a model that includes both constraints and transformations.

Ah, so you still have an underlying form. That was what I wondered about,
because otherwise phonology becomes nonsensical.

Hence my repeated call for a combination rule-and-constraint
grammar. (Wondering about possible theses many years down the road,if I
decide to pursue my doctorate. . . .)
