Yeah, I know I've been punting on this one so far but we should
probably get the discussion started.

Do you have any specific examples of validation that you may want or
need to do?  That may help frame the requirements.

Some things that come to mind that sites *may* want to apply custom
validation policies to:
- Stem creation (name)
- Group creation (name)
- Attribute add|mod|del
- Member addition (restrict membership to certain subject types?)

Anything else?

This, or something like it, is a possibility.  

This reminds that an earlier incarnation of Grouper during the months
before 0.5 would have made this trivial -- while making a lot of other
things harder.
