My personal goal would be to remove te necessity to inherit from
BaseObject. If anything like it is required, the object should rather
implement an interface.

Personally I'm not interested, I'd rather edit an XML file than annotate
classes. Others? You can also ask at the users list.
I have thought a bit about the AnnotationSourceProvider class. It could be
split in two parts:
- A general AnnotationSourceProvider which reads annotated classes (this
would be in the generator). It would have an annotation processor
configured in, which translates the annotations to a source tree.
The annotationProcessor interface would also live in the generator. It
would get e.g. a list of annotated classes which themselves contain the
annotated methods (and members, but personally I do not think annotating
members is a good idea) and would be responsible to create a source tree
from the annotated classes. General helpers (e.g. add all annotation
attributes as attributes of an elment in teh source tree) would also live
in the generator.
- The annotation processor and the specific annotations would be part of
the templates.
