  58  * Of course, with these new interfaces comes the data required to keep the state required
  59  * by these interfaces. So, basically, the pointers contain the data associated with
  60  * a release. If you use the data associated with release 3 in a release 2 object, you'll

 130  *
 131  *  * The set of interfaces accessible on an object through
 132  *    IUnknown::QueryInterface must be static, not dynamic. This means that
 133  *    if a call to QueryInterface for a pointer to a specified interface
 134  *    succeeds the first time, it must succeed again, and if it fails the
 135  *    first time, it must fail on all subsequent queries.
 136  *  * It must be symmetric ~W if a client holds a pointer to an interface on
 137  *    an object, and queries for that interface, the call must succeed.
 138  *  * It must be reflexive ~W if a client holding a pointer to one interface
 139  *    queries successfully for another, a query through the obtained pointer
 140  *    for the first interface must succeed.
 141  *  * It must be transitive ~W if a client holding a pointer to one interface
 142  *    queries successfully for a second, and through that pointer queries
 143  *    successfully for a third interface, a query for the first interface
 144  *    through the pointer for the third interface must succeed.
