Define a new code for "usage-context-type": "agreement-scope" - "Describes the level and scope of agreement represented within the artifact.  Appropriate values can be found in the xxx value set" (value set defined and named below) Define a new code system (and whole-system value set) called "usage-context-agreement-scope" with the following codes: "realm-base" - Defines use-case independent foundational expectations for exchange within a particular country or jurisdiction.  Should be accompanied by a jurisdiction.  Commonly used as a 'base' for more restrictive artifacts. "knowledge" - Defines use-case-specific information or guidance that is relevant to a specific business or health domain but is not mandated for particular use. "domain" - Defines use-case-specific requirements for a specific business or health domain.  May vary in jurisdictional scope from international to small region and in business scope from broad to narrow "community" - Sets contractual or business expectations for systems participating in a particular exchange community "system-design" - Documents the specific capabilities of a single system as "available" for purchase or use.  May have some variability reflecting options that can be configured "system-implementation" - Documents the specific points of a single production system or endpoint.  This may be time-specific - i.e. reflecting the system "as it is now" or as it was at some point in the past    Add this code system to the big example value set of all UsageContext value codes.
