Union of http://hl7.org/fhir/us/physical-activity/StructureDefinition/reference-rest-or-logical and http://hl7.org/fhir/us/physical-activity/StructureDefinition/reference-rest-or-logical

This is the set of resources that conform to either of the profiles Reference - RESTful or Logical (http://hl7.org/fhir/us/physical-activity/StructureDefinition/reference-rest-or-logical) and Reference - RESTful or Logical (http://hl7.org/fhir/us/physical-activity/StructureDefinition/reference-rest-or-logical). E.g. what you have to deal with if you get resources conforming to one of them

Structure

Name	Flags	Card.	Type	Description & Constraints
Reference	C	0..*		A reference from one resource to another ele-1: All FHIR elements must have a @value or children ref-1: SHALL have a contained resource if a local reference is provided PA-ident-1: reference or identifier must be present PA-ident-2: If reference is not present, display must be present
extension		0..*	Extension	Additional content defined by implementations ele-1: All FHIR elements must have a @value or children ext-1: Must have either extensions or value[x], not both
reference	SΣ	0..1	string	Literal reference, Relative, internal or absolute URL ele-1: All FHIR elements must have a @value or children
type	Σ	0..1	uri	Type the reference refers to (e.g. "Patient") Binding: ?? (extensible): Aa resource (or, for logical models, the URI of the logical model). ele-1: All FHIR elements must have a @value or children
identifier	SΣ	0..1	Identifier	Logical reference, when literal reference is not known ele-1: All FHIR elements must have a @value or children
extension		0..*	Extension	Additional content defined by implementations ele-1: All FHIR elements must have a @value or children ext-1: Must have either extensions or value[x], not both
use	?!Σ	0..1	code	usual | official | temp | secondary | old (If known) Binding: ?? (required): Identifies the purpose for this identifier, if known . ele-1: All FHIR elements must have a @value or children
type	Σ	0..1	CodeableConcept	Description of identifier Binding: ?? (extensible): A coded type for an identifier that can be used to determine which identifier to use for a specific purpose. ele-1: All FHIR elements must have a @value or children
system	Σ	0..1	uri	The namespace for the identifier value ele-1: All FHIR elements must have a @value or children Example General: http://www.acme.com/identifiers/patient
value	SΣ	1..1	string	The value that is unique ele-1: All FHIR elements must have a @value or children Example General: 123456
period	Σ	0..1	Period	Time period when id is/was valid for use ele-1: All FHIR elements must have a @value or children
assigner	Σ	0..1	Reference(Organization)	Organization that issued id (may be just text) ele-1: All FHIR elements must have a @value or children
