right. we need to be able to associate svg drawn shapes with data so the user
can click on something (like a class or association) and select it. we aslo
need to be able to associate widgets with UML geometries and standard
semantic metaphors. then there's that whole extensibility thing (being able
to create new visual metaphors for new concepts, like aspectJ aspects).

i thought that in previous discussion, we had admitted the requirement for
free-drawing capabilities - to a degree. i think it would be worthwhile to
allow developers to add miscellaneous text to a diagram and maybe simple
block shapes and what have you.
