For the interpreter QAB, the sign variable q need only range over the syntactic domain S = {"A", "B", "i", "u"} and the relation variable R need only range over the object domain O = {A, B}, so long as the latter objects remain subject to analysis as sign relations. These requirements can be accomplished as follows: | For the interpreter QAB, the sign variable q need only range over the syntactic domain S = {"A", "B", "i", "u"} and the relation variable R need only range over the object domain O = {A, B}, so long as the latter objects remain subject to analysis as sign relations.
