"A CDA document is comprised of a header and a body. The header identifies and classifies the document; provides information on authentication, the encounter, the patient, and the provider; and sets the context for the document as a whole. The body contains the clinical report, and is conceptually divided up into nested sections, each containing a narrative block to be rendered along with structured entries and external references." - HL7 CDA, ClinicalDocument "A set of healthcare-related information that is assembled together into a single logical package that provides a single coherent statement of meaning, establishes its own context and that has clinical attestation with regard to who is making the statement. A Composition defines the structure and narrative content necessary for a document. However, a Composition alone does not constitute a document. Rather, the Composition must be the first entry in a Bundle where Bundle.type=document, and any other resources referenced from Composition must be included as subsequent entries in the Bundle (for example Patient, Practitioner, Encounter, etc.)." - HL7 FHIR, Composition

"Document sections can nest, can override context propagated from the header..., and can contain narrative and CDA entries." HL7 CDA, ClinicalDocument Section "The root of the sections that make up the composition." HL7 FHIR, Composition.section
