    <comments value="Considerable care must be used when using nullFlavor in this context of FHIR - more than
     any other concept, this is tied to the way v3 works, and FHIR is quite different. For
     instance, there is no notion of a &quot;proper value&quot; as opposed to any other value
     in FHIR. a NullFlavor should be understood to mean, &quot;why information is missing&quot;,
     and the nulFlavors OTH, NINF, PINF, and TRC should not be used."/>

Usage note: every effort has been made to ensure that the examples are correct and useful, but they are not a normative part of the specification.
