Data Type Profile: ruid: HL7 Reserved Identifier Scheme

HL7 Reserved Identifier Scheme (RUID)\nA globally unique string defined exclusively by HL7. Identifiers in this scheme are only defined by balloted HL7 specifications. Local communities or systems must never use such reserved identifiers based on bilateral negotiations.

HL7 reserved identifiers are strings that consist only of (US-ASCII) letters, digits and hyphens, where the first character must be a letter. HL7 may assign these reserved identifiers as mnemonic identifiers for major concepts of interest to HL7.

Usage:

• Use this PrimitiveType Constraint: CD: ConceptDescriptor (V3 Data Type), II: InstanceIdentifier (V3 Data Type) and SC: CharacterStringWithCode (V3 Data Type)
