Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of its narrative along with other profiles, value sets, etc.</td></tr><tr><td>MessageHeader.language (language)</td><td><a href="CodeSystem-concept-map-relationship.html#equivalent" title="equivalent">is equivalent to</a></td><td>MessageHeader.language</td><td>Element `MessageHeader.language` is mapped to FHIR R4B element `MessageHeader.language` as `Equivalent`.
Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically.

Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.</td></tr><tr><td>MessageHeader.contained (contained)</td><td><a href="CodeSystem-concept-map-relationship.html#equivalent" title="equivalent">is equivalent to</a></td><td>MessageHeader.contained</td><td>Element `MessageHeader.contained` is mapped to FHIR R4B element `MessageHeader.contained` as `Equivalent`.
