This oid is used as an identifier II.root to indicate the the extension is an absolute URI (technically, an IRI). Typically, this is used for OIDs and GUIDs. Note that when this OID is used with OIDs and GUIDs, the II.extension should start with urn:oid or urn:uuid: 

Note that this OID is created to aid with interconversion between CDA and FHIR - FHIR uses urn:ietf:rfc:3986 as equivalent to this OID. URIs as identifiers appear more commonly in FHIR.

This OID may also be used in CD.codeSystem.">Uniform Resource Identifier (URI)</a>/urn:oid:2.16.840.1.113883.4.642.40.44.22.67</p><p><b>version</b>: 1.0.0-ballot3</p><p><b>name</b>: Evidence_for_Results_for_Add_on_Amlodipine_at_6_weeks_in_GroupAssignment_Quadpill_vs_Candesartan</p><p><b>title</b>: Evidence for Results for Add-on Amlodipine at 6 weeks in GroupAssignment: Quadpill vs. Candesartan</p><p><b>citeAs</b>: </p><div><p>Evidence for Results for Add-on Amlodipine at 6 weeks in GroupAssignment: Quadpill vs. Candesartan [Database Entry: FHIR Evidence Resource].
