ISyndicationInfo is a new interface. I'm tempted to use zope.schema  
directly on this but I suppose that does tie any implementation to  
zope.schema rather maybe annotated Python tyes. Thoughts?

Regarding zope.annotation - IAttributeAnnotatable creates a new object  
within the folder but I'd rather not have the SyndicationInfo visible  
within the ZMI but IAnnotations only uses a dictionary and so less  
suitable for storing multiple values. If I go the AttributeAnnotatable way  
is it okay to use Persistent rather than SimpleItem as long as  
manage_fixupOwnershiAafterAdd is provided? Or is that too kludgy and  
preferable to work on my current adapter to provide attribute access to an  
Annotations dictionary?
