I also agree.

I do not see why we need choice_expression and choice_relation RM
4.4(2.1/3,2.2/3).
Wouldn't simple_expression suffice in (3.2/3)?

membership_choice ::=3D simple_expression | range | subtype_mark

Are there any sensible uses for (boolean) choice_relations? I might
imagine some use of choice_expressions for modular types.

X in A > B and C | D .. E | Subrange  ??? doesn't look very sensible
to me

Examples please.
