Say I have a model with a supertype rule:
Options:
'{'
members+=Member
(',' members+=Member)*
'}';
Member:
A | B | C | D | E | F;
RequiredMembers:
A | B | C;
I want to write a validation method for "Options" where I check if the "members" feature has a entry for each of the RequiredMembers.
The example above is just pseudo code, the real live code is a bit mode complicated, I can't put the required members in "Options" and chain them with the & operator without forcing an order in the required members.
How can I get get the members in RequiredMembers from emf so I can use this info in my validator.

Hi rach DSL has a grammar access which offers such information. But
AS long AS you don't come up with a real world example it is hard to
tell if this will help you. You may have to debug into the stuff to
see what to do exactly.
