You mean something like this?

     // someFile.proto
     syntax = "proto2";

     message SomeType {
       required int32 x = 1;
       required int32 y = 2;
       optional string label = 3;
     }

     message AnotherType {
       required SomeType xy = 1;
       required int32 z = 2;
     }


     // foobar.d
     import "someFile.proto" : SomeType, AnotherType;

Because that would be seriously awesome.
