cond

<cond>

<cond> (conditional feature-structure constraint) defines a conditional feature-structure constraint; the consequent and the antecedent are specified as feature structures or feature-structure collections; the constraint is satisfied if both the antecedent and the consequent subsume a given feature structure, or if the antecedent does not. 18.11 Feature System Declaration
Module	iso-fs — 18 Feature Structures
