[Zope-CMF] How to attach own properties to existing portal types (like metadata does)?

Hi,

I'd like to attach additional properties to existing portal types. 
These properties describe (store information) about additional 
functionality independantly of the content type.

Existing and future portal types need not to know about this 
functionality. 

The functionality has nothing to do with the metadata 
functionality. That's why I don't want to integrate the properties 
into it. I'd like to implement a new tool handling this 
functionality.

I searched the CMF mailing list about discussions concerning
'aspect bags', 'mementos', 'mixin classes', but didn't find
any information about the status quo in CMF 1.3beta2.

I looked at the CMF 1.3beta2 code but missed the point, how
to achieve such behaviour :-( [possibly caused be the lack of 
my own brainpower :-) ].

Does someone have any pointers where to look, where to find 
examples, which interface to implement to attach such properties, 
etc.?

Sorry, was not able to have a look at http://cmf.zope.org because 
it's out of service.

Greg
