Resolution to OMG Issue ALF11-2 was not fully implemented

[seidewitz]

OMG Issue ALF11-2 loosened the definition of what a "collection class" is. The resolution defined a collection class as a class having a constructor of the same name, taking a single sequence argument, and a "toSequence" operation, returning a sequence of the same type as the constructor argument. The reference implementation had already adopted the approach of using the return type of the "toSequence" operation to identify the sequence type of a collection class, but the v1.0.5 tracking release did not include the change to the underlying definition of a collection class (retaining the tighter definition that a collection class had to be an instantiation of one of the standard library collection classes).
