I'm not very comfortable with this, I think it would better if such attributes started with core. or even c.

I also think it would be better to enforce storage in a completely separate map rather than making this part of the key 
name. Perhaps that's too fussy.

What would vnd stand for?  My preference would be not have this but just something like acme.myprop instead.

It might be worth putting a limit on the amount of data stored, to stop any region module massively filling up the space.
