The compiler does not resolve the name space.

I have

A.proto
message A {
    message innerA {
    }
}

B.proto
import "A.proto";
message B {
     A.innerA something = 1;   // error here: Namespace A for type innerA not defined
}

Is it because I did not configure it correctly or the feature is not implemented yet?

I use the official python compiler and it seems to be working fine.
