Hi Christian,

no problem for the delay ;)

Before answering your questions I need to provide some more context.
Currently, I'm converting graph transformations into a Boolean
representation to execute the graph transformations symbolically. For
this purpose I need to parse attribute match expressions and attribute
conditions found in the LHS, and attribute assignment expressions
found in the RHS. Now, the tool that executes the transformations
symbolically might be used by other developers as well, so it's hard
to say how they are going to use it. With the context explained, I can
now  answer your questions.

Currently, I'm using dynamic EMF models, but I would expect that at
some point in the future generated model classes could be used. I
didn't expect a difference here, so I'm curious how this changes the
handling of enums?

I anticipate the use of enums in attribute expressions and attribute
conditions on the LHS, and assignment expressions on the RHS. On the
LHS and the RHS, both constant expressions and compound expressions,
for example, the one you provided above, might be used.
