UML22 — manage simultaneity of events

Issue 1: to have the possibility to manage simultaneity of events, and be able to

trigger a transition by a condition on several events. By this way, the triggering

condition of a transition may be specified through an event formula such as: (e1 and e2) or e3

This point we then involve to relax a constraint on the semantics of RTC and to introduce then

the possiblity to dequeue several events of the queue at the same time. May it be just an

additional open variation semantics point?

Simultaneous events and transitions triggered by a logical combination of events require a major modification or enhancement to the current Run-To-Completion semantics, where events are handled one at a time. This therefore needs to be postponed to a more major revision, when we will have time to investigate this proposal and see if and how it can be accommodated.
