; *** Identity BE ***
; For now, exclude gerundive complements, to avoid semantically anomalous
; reading for "Kim is sleeping"
; DPF 08-Jan-00 Made COMP be nom_rel instead of reg_nom_rel, to allow "Tuesday
; is my last day" and "that's him".
; DPF 22-Feb-01 - Added ALTMIN restriction on SUBJ to prevent free relatives
; from appearing in subject position, to get the contrast of "I admire what
; you are" vs. "*I admire what are you" (and cf. "I admire what is best").
; DPF 26-Aug-01 - Added MIN nom_rel to SUBJ, like for COMP, to avoid having
; measure_nps in subject position.
; DPF 19-Oct-02 - Removed identification of PT on SUBJ and COMP, since
; this blocks "it is I/me" "that's me" etc.
; DPF 27-Apr-03 - Removed [COMPS..PRD -] since this prevents 'today is December
; third', and it's not clear what it was blocking.  (Nor is it clear why
; 'third' has to be [PRD +].)
; DPF 10-Jun-03 - Try identifying SORT values of subj and comp.
; DPF 5-Sep-03 - Don't understand comment of 22-Feb-02 above, but clearly
; free relatives can be subjects of identity copula: "What he does is your
; problem".  So removed this constraint.
; DPF 18-dec-03 - Keeping identity of SORT values is too hard - e.g. "The
; cabin is a good place to stay".  
; DPF 30-aug-04 - Removed PT real_pron from SUBJ, since it
; prevented "consultant hiring is a disadvantage" with N-N-cmpnd subject NP.
; Leave on COMPS for now, to continue to block spurious analysis for
; "the boy is fishing."
; DPF 19-nov-04 - Removed identification of SUBJ..AGR with SUBJ..--SIND since
; want "three kilometers" measure-NP to be syntactically singular, even though
; semantic index comes from "kilometers" which is plural.
; DPF 05-nov-05 - Added CASE non_obliq to COMPS to block idiomatic detless NPs
; as in 'on top' from giving "*Kim is top."
; DPF 13-nov-05 - But sadly this also blocks "This is why we suffer".  So
; instead try requiring non-empty SPEC, where detless NPs have SPEC < >.
; DPF 28-oct-06 - Removed PT real_pron from COMPS, since we want to
; allow "The reason is the fishing."  No longer getting as much spurious
; ambiguity, for example with "The boy is fishing."  See if too much remains.
; DPF 25-may-10 - Re 13-nov-05: No longer necessary, and SPEC *cons* was
; blocking "the cost is $100."
; DPF 04-jun-10 - Added COMPS..CASE non_obliq to prevent bare-sg nouns in PET,
; as in "*Kim is being in Paris"
; DPF 2010-sept-08 - Re 04-jun-10: But we also want to use CASE to exclude
; spurious analysis for "Where is Kim".  So change CASE to nom_or_obliq, and
; instead use HEAD mobile to exclude bare-sg nouns in PET (which does not
; currently attend to constraints in idioms.tdl).
