Modeling the Dialogs and Wizards for an application is a good thing to do. If you consider the model to represent the agnostic description of what UI bits the app needs in order to function then it makes perfect sense to say something along the lines of:
"My Contacts app needs the Contacts window, an Open Contact List dialog and
a Create Contact wizard"
This is a proper indication to anybody wishing to implement that
application on *any* platform they they'll need to supply the rendered UI
for those components.
Before getting into the model specifics I'd like to look at what Dialogs
and Wizards *are*...
- They show up in their own windows
- They both represent requests to gather information from the User
- They're transient; opened by the IDE -> closed by the User
So, the specifics of how they're modeled aside, how do the elements
communicate the results back to the IDE ? The pattern for creation seems
fairly straightforward; add all necessary input parameters into the
'localContext' used to render the Dialog / Wizard. It's less clear how the
IDE (app) then retrieves the result.
For the model itself how about both MDialog & MWizard extend MWindow (since
they show up as windows). Whether or not we also need the MWizard to have a
specific collection of MWizardPages or if we can just have the logic
manipulate an MPartStack using ids is open for me, there's are good reasons
for either way. The MApplication would be extended to have two new
collections; 'dialogs' and 'wizards'.
Note that there's a beneficial side-effect of modeling the Dialogs /
Wizards; this structure makes it completely natural to embed parts into
both Dialogs and Wizard(page)s. One of the initial problems I faced during
my demos for this was that I had to 'fake' the embedded part being in the
model (see EModelService#hostElement); if the MDialog were modeled this
would no longer be an issue.
Thanks folks, this is exactly the type of discussion I was hoping for,

Not strictly speaking but maybe we need some extra attributes later on
there so I would model it explicitly.
Rethink my proposal would change to:
MWizard extend MElementContainer<MWizardPage> {
}
MWizardPage extends MPart {
}
For MDialog we could also think of
MDialog {
MPart part
}
which is probably better alignment with a MWizard then.
