CDA R1 and R2 use the original Datatypes specification. There's now a new R2 specification that should pass final HL7 and ISO approval by Sept. It incorporates numerous clarifications, enhancements and corrections


  • Ensure that CDA R3 is clearly defined to use Datatypes R2, not R1


The new datatypes support several use-cases not supported by R1. In addition, datatypes R2 eases implementation by UML software.
