MF_ATTRIBUTES_MATCH_THEIR_ITEMS

Check whether all the attributes in pTheirs exist in pThis and have the same data, where pThis is the object whose Compare method is being called and pTheirs is the object given in the pTheirs parameter.

MF_ATTRIBUTES_MATCH_ALL_ITEMS

Check whether both objects have identical attributes with the same data.

MF_ATTRIBUTES_MATCH_INTERSECTION
