The mappings for `Task.text` do not cover the following types based on type expansion: div, status. Contained resources do not have 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 in formation is added later.

The mappings for `Task.relevantHistory` do not cover the following types based on type expansion: display, identifier, reference. The standard extension `alternate-reference` has been mapped as the representation of FHIR STU3 element `Task.relevantHistory` with unmapped reference targets: Provenance. This element does not point to the Provenance associated with the *current* version of the resource - as it would be created after this version existed.

The mappings for `Task.text` do not cover the following types based on type expansion: div, status. Contained resources do not have 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 in formation is added later.
