 * 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.

 * To support documents, and also to capture the EN13606 notion of an attested commit to the patient EHR, and to allow a set of disparate resources at the information/engineering level to be gathered into a clinical statement
