The standard for this IG is to send only the information required for the recipient to interpret the request for a service.  However, there is no provision for sending less than the elements required by a specific exchanged resource to meet the profile definition.  Will include some guidance on the ability to use a Smart on FHIR to app to allow patients to restrict the exchange of information that is not required to interpret the intent of a specific resource (e.g. remove address and/or telephone number from the patient resource prior to sending it to a community based organization) but has the potential to cause social risk.
