When a DTR app wants to create a PAS Bundle for submission is not clear where to get the required PAS Requestor Organization. A request such as ServiceRequest contains a property called "requester" that can be an Organization or a PractitionerRole, but it seems more likely to be a Practioner. The PAS Encounter contains a "serviceProvider" property, but it is not required. It would be helpful if the DTR IG could provide some guidance on where to locate the required information for PAS.
