[developers] Paraphrase grammars and SEMI's

[Dan Flickinger]

I'm in agreement with the rest of you.  The internal type hierarchy is also (necessarily, I think), more subject to restructuring as the quest for ever better linguistic analysis proceeds.  I think it's useful to view the paraphrase task as related to the MT task, for which the SEM-I MRS is essential.

Thanks.  That's another good reason.
