obsolete_collection of board eligible orthopedic surgeons in trauma care true A collection of humans, all of which bear both an orthopedic surgeon role and an orthopedic board eligibility role and participate in a trauma care process Initially, we used the SubClass restriction, with 'only' after 'is aggregate of' as an equivalent to restriction, which fully defines this set.

For our data management purposes having the restriction as an existential restriction is totally sufficient, so we go with this. John Judkins failed exploratory term
