Dear Gaelle,

thank you for your input. My comments in line...

The composition could also relate to having a single child, for example if
a Container simply presents a subcontainer (not very frequent, admittedly)

No objection to that

I would prefer to have them as separated events, as in multimodal
interfaces, it might be the case that there are different ways to
select/deselect elements, not necessarily with all modalities supporting
all possibilities.

a) A TriggerEvent triggers a Behaviour, i.e. some transformation of the
state in terms of availability of resources. The TriggerEvent does not
trigger an AIU: It is the AIU which provides the support for the generation
of TriggerEvents
b) my understanding is that this should be the role of an UpdateEvent. A
trigger event might result in enabling or activation another AIU through a
presentation mechanism, if it produces some effect on the state of the
application which makes the interaction progress.

This relation should occur through Behaviour, where a Task would be a type
of Behaviour. In a sense, we should publish the whole collection of
metamodels (in particular Event and Behavior) to make the document
self-contained, but we agreed to start by publishing only the AUI + Commons
part.

Hope this helps
