you are half right but for the wrong reason. think about the word
'interface' for a moment! its illogical for a interface to define a
protected/private method (don't argue the gods have already decided :-)
and its therefore been decided that interfaces are not allowed to have
access types defined.
the bit where you are wrong is that its quite feasable to have private
or protected methods - heres a quick grep ('static private function') of
some of my code:
include\class\ExchRates.class.php(164): static private function
getConstants()
