There's a strict interfederation requirement lurking here: Scope is an
entity characteristic that is best expressed at the role level.

Another interfederation requirement: explicit regexp="false"

The primary concern here is the discovery interface. As I mentioned to
Rod at one point, MDUI DisplayName should be strongly recommended, if
not required. The InCommon Federation falls back on
OrganizationDisplayName as a last resort but considering the
complexity of the latter in the UKF, that could present some problem.

On the SP side, MDUI DisplayName is likewise a strong recommendation
(if not required).

How do we increase the likelihood that MDUI DisplayName is globally
unique? I think it's nontrivial to enforce uniqueness at the consumer,
but that's exactly what you need, especially on the discovery
interface.
