well-defined assignment semantics (T::operator=(const T&) or equivalent);●
well-defined equality semantics (T::operator==(const T&)).●

Example
This examples exercises a set of RWCStrings.
#include <rw/tvhset.h>
#include <rw/cstring.h>
#include <rw/rstream.h>
main(){
RWTValHashSet<RWCString> set(RWCString::hash);
set.insert("one");
set.insert("two");
set.insert("three");
set.insert("one"); // Rejected: already in collection
cout << set.entries() << endl; // Prints "3"
return 0;
}
Program output:
3
