CHK0057: An activity should refer to at least 1 procedure, BC surrogate, BC or BC category An activity can be of one of these types

Procedure (0..*)
BiomedicalConcept (0..*)
BiomedicalConceptCategory (0..*)
BiomedicalConceptSurrogate (0..*)

This means that an activity must reference at least one of these classes. I'm not sure whether an activity can reference a mixture of different types.
