ZF INDUCTIVE DEFINITIONS: Simplifying the type checking for mutually
recursive datatypes, especially with monotone operators
ZF/add_ind_def/add_fp_def: deleted as obsolete
ZF/add_ind_def/add_fp_def_i: now takes dom_sum instead of domts. We no
longer automatically construct a sum of separate domains, but could use a
sum-closed set such as univ(A).

ZF/intr_elim/elim: now "folds" definitions of the mutually recursive sets!

lcp [Mon, 21 Nov 1994 14:06:59 +0100] rev 724
ZF/indrule/mutual_ind_tac: backtracks using DEPTH_SOLVE to be certain of
solving the subgoal. Entire tactic is enclosed in DETERM to prevent
backtracking between subgoals.
