package visibility

Hi, we currently have private, protected and public visibility for properties and methods. however since we requently make use of container or will be increasingly emulating multiple inheritance via __call() I propose we also add "package" visibility as uml2 features. the idea here is that the given property/method should only be called by code that is part of the given package and not by the user. what do others think? in true uml style i would like to leave the discussion of how to handle the syntax of package visibility to a possible later discussion. regards, Lukas PS: uml sucks :-)
