Well. I still believe the best way to support the DCMI-supplied name is 
not to use it as a method name. But as my proposal was to remove the 
'Creator' method I can live with a method 'misusing' the name 'Creator'.


I hope everybody can live with these methods in the long run:

listCreators() -- sequence of Dublin Core Creator elements
Creators() -- string "; ".join( self.listCreators() )
Creator() -- alias for Creators()
listContributors() -- sequence of Dublin Core Contributor elements
Contributors() -- string "; ".join( self.listContributors() )


Regarding migration that would mean:

Creator() might return more than one creator and manipulating the owner 
wouldn't have any effect. That breaks some existing code but should work 
in most cases.

In CMF 1.5 Contributors() could be an alias of listContributors(). 
People are encouraged to switch to listContributors(). In CMF 1.6 
Contributors() would return a string like Creators().


Does that make sense?
