Dir-spec extrainfo attributes vague about publisher
Currently extrainfo descriptor attributes like...
- bridge-stats-end
- dirreq-stats-end
- entry-stats-end
- cell-stats-end
- exit-stats-end
... all have a copy-and-pasted description of each other. I guess that 'entry-' attributes apply to guards and 'cell-' apply to everyone, but the spec doesn't say so making this just a guess.
Ideally all of the descriptor attributes would explicitly say who publishes them.
