Clarification IfcRelAssignsToActor> ActingRole and IfcPerson/IfcOrganization>Role

The “5.1.3.22 IfcRelAssignsToActor - IFC 4.3.2 Documentation” relation contains an attribute “ActingRole”. Is that attribute adhering to the roles assigned to “IfcOrganization”/ “IfcPerson” to which the “IfcActor” is referencing (i.e. should it inherit from Organization Role or Person Role?), or is it freely populated as something not directly connected with the above mentioned?

Thank you,
