Existing Wording: A set of healthcare-related information that is assembled together into a single logical document 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.

Proposed Wording: A composition defines the structure for a set of healthcare-related information that is assembled together into a single logical document 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. While a Composition defines the structure, it does not actually contain the content: rather the full content of a document is contained in a Bundle, of which the Composition is the first resource contained.

Comment:

The distinction between the document as assembled, vs the composition as a structure and "pointer" to the resources, is fuzzy in this opening paragraph, which makes it sound like the composition is itself the Document, whereas elsewhere the text clarifies that the document is actually a Bundle that includes Composition as one resource, plus other resources. The proposed wording tries to clarify more precisely that the composition defines the structure. I think of the Composition as being like a document's Table of Contents with hyperlinks, but not the document itself: is that a fair analogy?
