The only reason why those templates are static is so users can overwrite
the exception messages. That was useful when we didn't have a handy
translator, but now that we can define a translator through the Factory,
this is not needed anymore.
Besides, having those properties public adds complexity to the code.

According to the official documentation [1] the correct way of writing
the "inheritDoc" tag is with the uppercase "D".
