{\em Mapping(T,S,...)} denotes the class of objects which are
mappings from a source domain ({\em S,...}) into a target domain {\em T}.
The {\em Mapping} constructor can take any number of arguments.
All but the first argument is regarded as part of a source tuple
for the mapping. 
For example, {\em Mapping(T,A,B)} denotes the
class of mappings from {\em (A,B)} into {\em T}.
{\em Mapping} is a primitive domain of \Language{} which cannot be
defined in the \Language{} language.
