A validation/constraints framework that would make everybody happy
would be Turing complete; therefore protocol buffers don't include it.
It is simple enough to write a bool IsWellFormed(const MyMessage&);
function.

Sorry, but validation of this sort is not part of protocol buffers. You'll need to write validation routines separately. We made a conscious decision not to try to support validation in the .proto language itself because it seemed like it would require a turing-complete language to express arbitrary validators, and we wanted to keep things simple.
