Probably and most likely, yes.

As XML which the arch templates are. Think of something similar to the 
way glade works for gtk, but much more generic.

It has to since it has to be displayed.

The view glue and implementation information is obviously absent from 
the class diagram. That is not a mistake. It's just that the view code / 
system will, most likely, be the most complex part of the installer. If 
we didn't have to worry about multiple UIs, multiple archs, changing 
steps and stages, and generics, we'd be on better ground, but that would 
be directly against our design goals. :)
