UML25 — Location: p. 330 Deferred Events - Value of Deferred Events

I think this is also new specification in UML 2.5. If so, it should be added to the summary of new specifications at the beginning of the document.

This is a feature with some value. The question is the following. Does this feature brings more value than the complexity it adds to the specification and the tools that supports UML? My view is that such a feature adds more avoidable complexity to the tools. At the same time, the same behavior can be achieved using the already existing UML features. I would vote against this feature in favor of keeping the specifications less complex

The submitter is mistaken. Deferred events have always been a part of UML state machines.
