Martin, std::string may be called a descriptor as well, though this fact is not really important, is it? It is just an implementation detail.
In my humble opinion the answer is "message as a logical object is not changed". It is possible to modify some internals like reference counters in constant methods. What I've forgotten, C API does not use const, so const_cast is required.
