+/// \brief Set Type Specification
+/**
+This struct is used to specify an unordered_multiset specification.
+It is not a container, it is just a metaprogramming facility to
+express the type of a set. Generally, this specification will
+be used in other place to create a container.
+It has the same syntax that an tr1::unordered_multiset instantiation,
+except that the allocator cannot be specified. The rationale behind
+this difference is that the allocator is not part of the
+unordered_multiset type specification, rather it is a container
+configuration parameter.
+The first parameter is the type of the objects in the set, the
+second one is a Hash Functor that takes objects of this type, and
+the third one is a Functor that compares them for equality.
+Bimap binding metafunctions can be used with this class in
+the following way:
