This profile identifies the additional constraints, extensions, and value sets that build on and extend [Patient](http://hl7.org/fhir/R4/patient.html) that are supported. 

This profile is designed to set a core Patient standard for:
* Querying for records associated with a patient
* Record or update a record associated with a patient


#### Profile specific guidance
- Country of birth is represented using `Patient.extension` [birthPlace extension](http://hl7.org/fhir/R4/extension-patient-birthplace.html)
  - A system may use `address.text` if birth place address is not stored in discrete elements
- A patient's biological sex is represented as a separate Observation resource
