In addition, attribute names should come from the grouper_fields
table. In particular, there's no [effective|immediate|composite]
variants of a list field - that's a UI presentation thing.

So do away with [attr|list|priv]Name and just use the field names ? e.g.

dn: ...
add: members
members: subjectA
add: admins
admins: subjectA

That's (almost embarrassingly) straightforward - I was thinking that non-grouper consumers would want to identify attributes and lists (grouper types) so they would know what values to expect (subjects or strings). At first I thought we should include 'type' in the change representation, and had <type name>[attr|list]Name to identify default and custom attributes, e.g. baseAttributeDescription and memphisAttributeDescription to provide separate attribute namespaces. I wasn't looking at grouper_fields, but rather the API, perhaps I thought too much :)

I don't think that the audit/notification systems need to be signaled in-band about the nature of each attribute. Just as with LDAP objectclasses or any other container with explicit schema, an application will need to know, through configuration or coding, how to use the data it's dealing with. An xml-export of the group registry's metadata provides a nice human- and machine-readable description perfectly suited to this purpose.
