BTW, JPA spec defines a concept of a "transient" attribute, so this
will be coming to Cayenne as well. Although as others noticed this is
primarily a non-functional (although useful) convenience.

So far so good, but it would be fine if I could see them in
the modeler/map-definition. It would be very helpful
for the project-informations within the project-team.
We have the separation between DbEntity and ObjEntity.
One of the benefits of this kind of structure is that you
can have attributes in the ObjEntity that are not part
of the DbEntity. This attributes are non persistent.
With these attributes an ObjEntity is improved to a BusinessObject.

If these attributes are the same for every entity, you can do this by
editing the templates which are used to create the entity classes.
Otherwise, I don't understand why editing the subclass isn't the
easiest approach.
