property for grobs.

What is so special about DOM-id's that would warrant code hand-tailored to  
them and nothing else?  I am pretty confident that this is fringe  
functionality.  And when suddenly somebody figures that he'd like a COPE-id  
on something put out via SVG, what then?  Copy, paste, repeat?

I think it would make sense to program this sort of functionality with a  
bit more focus on reuse.  So that the next time someone wants to add  
another kind of Id, possibly even to a different backend, the code does not  
need reinventing or at least recopying.

Can you think about how this could be more general?  It would have the  
advantage for you that people would stop pestering you to explain what a  
DOM-id is since that would then just be a detail relevant to your  
application of some more general XML-tagging algorithm.
