delimitation rule #20

Atmosphere between expressions is optional on the current specification of Pose.

expressions  = (atmosphere* expression)* atmosphere*

According to this rule, (1a) can be interpreted same as (1 a). (01) is (0 1). Is this by design intent or should it be invalid error?

It's another mistake. It should be something like:

expressions = atmosphere* expression? (atmosphere+ expressions)?

The current grammar is totally ad hoc. It's my fault. We should use some consistent variant of BNF.
