I have to get the message structure of a protobuf message transfered to me without the message's definition. Using UnknownFieldSet methods, I was able to get a string representation of the message as below:

1: "a"
2: {
   3:"b"
   4:"c"
}

What data structure does field 2 represent ? Using UnknownFieldSet.Field.getGroupList i was able to get the content of field 3 and 4, does that means field 2 has the "deprecated" group structure ?
