Agreed, without regulation titles become as worthless as the paper it is written on. Personally I would like to see some certification body take on the task of providing professional accreditation. Not per language mind you. That would be to specific and hard to keep up with. More, general computing concepts, mathematics behind computers, algo's, design patterns, business cases, etc. I doubt it would ever happen but one can hope right?
It would need to be country-based, but yes. I think the most important topic would be ethics and logic, since you're most likely affecting lives, especially in big corps.
