MW: Nothing quite like looking at the definition. And when I do I 
see that it is a bit lacking if you only look at the text. However,
if you look at the EXPRESS you find that it is an ABSTRACT entity
type (not my choice of use of the term here - this is part of the
EXPRESS language) and what that means is that this entity type has
no instances except those that are instances of its subtypes, which
is another way of saying it is exactly the union of its subtypes.

MW: There are three subtypes, class - which is defined as being
non-well-founded sets, relationship, for which effectively read
binary tuple, and multidimensional_object, for which effectively
read n-ary tuple. Is that operational enough?
