Type	text	Required	Categorization of external resources. Examples include: "ODM", "HL7-FHIR", "HL7-CDA", "HL7-v2", "OpenEHR-extract". Note: Extensible controlled terminology may be developed and published in the future.
Name	name	Required	The human readable identifier of the element or field in the external resource. Examples include : "ItemGroupDef" (for Type="ODM"), "Observation" (for Type="HL7-FHIR"), "substanceAdministration.doseQuantity" (for Type="HL7-CDA"), "OBX-5" (for field 5 ("Observation Result") for Type="HL7-v2").	The value must be an existing element name or field name for the specific document or message type provided in the Type attribute.
Attribute	name	Optional	Field provided by the Name attribute where the data or information can be obtained. Examples are "valueQuantity.value" or "valueQuantity.unit" for the case of an HL7-FHIR "Observation", "Repeating" for the case of an ODM ItemGroupDef element, "unit" for the case of an HL7-CDA doseQuantity, "Code" or "Name" for the case of field 5 (which is composite) of an HL7-v2 OBX message. The Name and Attribute attributes are meant to provide traceability documentation.	The Selection child element must correspond to machine-executable instructions for extracting the information from the resource.
