I could also live with this, in fact I'd be happy to support this  
proposal. I believe it would provide a more consistent story with the  
change of the labelling properties to annotations. I don't see it as  
a substantial change, and believe that if we can justify the change  
of the labelling properties, then we can justify the change of the  
documentation properties.
