Re[2]: [Zope-CMF] Re: Overriding title from DefaultDublinCoreImpl

O.K. What i'm trying to do right now is to develop a new class
LocDefaultDublinCoreImpl which is derived from LocalPropertyManager
and DefaultDublinCoreImpl. It just overrides the metadata attributes
and methods and uses localized ones instead. I can use this as a base
class (if it works) instead of overriding the DublinCore methods in
every class. 

Are there some complications to be expected?

When i override a method and add a new parameter, i think i would have
to set the added parameter as None by default, so that if someone
calls the method in the 'old style' it doesn't fail with e.g.
'expected 3 params, only 2 passed'.

Correct?
