X.501 could be clarified a bit in this area.

I would think they should be inherited if not explicitly
specified.

foo;lang-en should be X if foo is X

(where X is any of the above characteristics)

I would also think some restrictions upon changes are likely
appropriate.  I don't think it makes much sense to have a
non-collective subtype of a collective attribute.
