Do you mean comments which will actually be passed to the database  
engine? Is this for auditing or logging? If so, I'd suggest that maybe  
they are a completely different feature to CAY-400 since the core of  
Cayenne will have to understand how to apply them.

Although we could reserve certain keys (eg. cay-javadoc, cay- 
SQLcomment) generic key-values is going against the XML paradigm and  
it might be better to just have special GUI elements for special  
things like these.
