[arin-ppml] Draft Policy ARIN-2018-4: Clarification on IPv6 Sub-Assignments

Students in the case of a University or other school, or staff/employees in
the case of most organizations shouldn't be considered "temporary", how
about "ancillary". On the other hand guest or customers of an organizations
"temporary" seems an appropriate description and a timeframe of day or
weeks also seems appropriate.
