Hi Charlie,

Uids are wired up using the event machinery, so shouldn't need changes 
to content classes.

By default, uids are applied for all content with the IContentish 
interface   so as long as AContentObject provides that interface, it 
should get uids.  You can see this in event.zcml.

Originally, the tools did not do this, so for BBB you also need to check 
some properties in the annotation tool properties tab (I think): 'assign 
on add' and 'assign on clone'.
