Two types A and B are a model of the ExplicitInteroperable concept, if it is possible to derive a superior type for A and B, such that both types are embeddable into this type. This type is Coercion_traits<A,B>::Type.
In this case Coercion_traits<A,B>::Are_explicit_interoperable is Tag_true.
A and B are valid argument types for all binary functors in Algebraic_structure_traits<Type> and Real_embeddable_traits<Type>. This is also the case for the respective global functions.
