The UPDATE privilege on the attributeDef means you can assign it (well, you
might need more, but at least that). If you think we only need READ, then
you and I need to discuss on the phone so we can get on the same page.

Per our discussion on the dev call with Shilen, any stem STEMMER or CREATOR
can assign an attribute (they can UPDATE)

I think we need a group for this that you specify in (or
wheel)... lets see if I get to it. Someone will want to use member
attributes who is not wheel...

Yeah, or, e.g. for a permission you assign to a person in a role (membership
attribute), but you want to say that permission is only for a certain time of
day, from a certain ip range, on certain slices of the data, etc.

Anyways, this needs to get resolved at latest by the end of the next dev
meeting. If you want to discuss earlier, send me your available so we can
talk on the phone.
