Dear colleagues,

sorry for not participating the last two telcos. I just arrived back
this weekend from traveling and i am now trying to catch up with the

I really like the idea to specify the consumer/producer part by
interfaces and types as proposed by Paolo as it better separates
behavior and eases re-usability in other models.

Further on, i am in favor of separating input from output to ease user
interface distribution to output-only platforms. Thus, only input
interaction units should be allowed to produce events and a selection is
an input in my understanding.

Looking at Heiko's contribution i really like the straight-forward class
naming (container, output, input, edit, selection). For me Heiko's model
seems to be much more self-explainable than our current one in the document.

As Dave mentioned at the meeting in Lyon we require implementation
reports to proof support from the community. I think the more attributes
and concepts we include in the first document the higher will
be the barrier for others to support our proposal.

Maybe it would be worth to publish a first AUI document using a
condensed "core" AUI model just with the basic classes and "required"
attributes only?

By extended AUI models we then could specify advanced features such as
localization, constraints, documentation and so on as well as show
additional features of specific implementations of the model to help
readers to figure out an implementation that fits their needs.

Attached three images: a condensed core model based on Heiko's and
Paolo's suggestions, and two extended models: the extension to match the
current AUI document model(just the differences without attributes) and
the one that shows how our approach (MINT) considers the condensed model.
