the implemented_in is unnecessary; this should be the default.

Done.

Please ask Costin if this should be a string to string map

[jianli, 2015/04/22 20:18:21]

Yes, this was what I am told.

OK, what I was looking for is perhaps a way to specify that in IDL. (I know it
is doable in JSON). If not possible we'll have to enforce it in the code.
