The Foundation Document details the new approach in HL7 V3 :-

• HL7 V3 adopts an Object Oriented (OO) approach using Unified Modeling Language (UML) principles.

• Reduced Optionality. Limiting optionality is a primary goal of HL7 V3. Within HL7 V2.x, almost every field is optional.Optionality makes it harder to precisely define the semantics of a specific message and makes it virtually impossible to generate conformance claims for messaging.

• Conformance to HL7 V3 will be testable.
