 The DTR IG is a complex specification and these tests currently validate conformance to only
 a subset of IG requirements. Future versions of the test suite will test further
 features.

+Additionally, the DTR IG has two notable discrepancies in the 2.0.1 version, particularly in the RESTful capabilities by Resource/Profile section. First,
+v2.0.1's section on Coverage appears to be inconsistent with whether `context`
+and `patient` search parameters are supported by the CRD Coverage Profile or the
+DTR QuestionnaireResponse profile. The [CRD Coverage Profile](http://hl7.org/fhir/us/davinci-crd/StructureDefinition/profile-coverage) does not define search parameters, so this test suite tests for `read` capability of the CRD Coverage profile ONLY. Instead, this test suite tests for `read`, `create`, `update`, and `search-type` capabilities of the [DTR QuestionnaireResponse](http://hl7.org/fhir/us/davinci-dtr/StructureDefinition/dtr-questionnaireresponse) profile. Second, v2.0.1's section on Task capabilities does not appear to include a Supported Profile. For this test suite, the [CDex Task Profile](http://hl7.org/fhir/us/davinci-cdex/StructureDefinition/cdex-task-attachment-request) is used for validation.
