Proof step 30 from proof validref-subspec-samesubclasses-01 (conclusion)

⊦ validref(str0, r, ty, st) ∧ same-subclasses-contains(ty .jtelemtype .class, str, str0) ∧ tdname+∃(str0, ty .jtelemtype .class) → validref(str, r, ty, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 29:
tdname+∃(str0, ty .jtelemtype .class), same-subclasses-contains(ty .jtelemtype .class, str, str0), validref(str0, r, ty, st) ⊦ validref(str, r, ty, st)
