Replace with the following: "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.)." Add the following later on the Composition page: "It is acceptable for a Composition to contain only narrative (Composition.section.text) and no entries (Composition.section.entry)."
