I feel a bit thick, but I just don't get the VE model. I look into the
cdmmodel.genmodel file and I expect to see entities named Text, Label,
Button, etc., but I see nothing like that. Why? What is CDM actually a
model of? Where would I find the model objects that I am looking for?

The CDE model is only a base. It provides the visual annotations for a
model. The real implementation model that the VE is working on is
application dependent. For example, the Java VE uses the java model out
of org.eclipse.ve.java.core to model java classes. Then we use the
extensions of it in org.eclipse.ve.swt to model the SWT classes.
The CDE has no concept of Text, Label, etc. because those are domain
specific. Only the domain knows what model objects are available for the
domain. But the domain model doesn't know anything about the visual
representation on the VE. For example a model of java code has no
concept of being at location (100,100) on the white surface of the VE.
So that is what the CDE models, the extra annotations that are needed
for the VE to display but are not actually part of the domain model.
