Detailed Description

True if the given set is of a category declared to be iterator-defined.

Iterator-defined means that any set type of the category must have member functions begin and end, and two sets with the same traits are equal if the sequences of values provided by iterating over the elements are equal.

For example, this enables the "default" equality comparison functions in common_predicates.h.
