This is not possible. You have a set of elements of which some can be
ordered and some not. This leads to the situation that the set cannot
be ordered, i.e., the behavior is undefined. Every other
interpretation would have to introduce some defaults which are
strictly prohibited. Note that executing the events in a random order
or partially random order as yu usggest is different than the order
being undefined. People can easily avoid this situation by specifying
the priority attribute for all events.

Thanks,
Stefan
