obsolete_collection of trauma panel neurosurgeons true A collection of humans, all of which bear a neurosurgeon role and are designated as part of the trauma on call plan specification Initially, we used the SubClass restriction, with 'only' after 'is aggregate of' as an equivalent to restriction, which fully defines this set. However, given the number of collections in OOSTT this negatively affected reasoning time. For our data management purposes having the restriction as an existential restriction is totally sufficient, so we go with this. John Judkins terms merged
