https://fhir.nhs.uk/England/StructureDefinition/Extension-England-EndpointBusinessScenario	draft	0.1.0	2025-07-21	The Endpoint Business Scenario extension indicates if the endpoint is the main recipient for the message. In most cases, except for Service type 'GP', the entry should be 'Primary'. For Service Type of 'GP' the Primary endpoint will be used to receive messages from dispositions where the patient is being directed to their own GP and the GP needs to have direct access to the call information. The 'Copy' endpoint is only used for Post Event Messaging (PEM) to GP services.	This extension is a Directory of Service (DoS) use case, Use to differentiate between primary message recipients and copy recipients, particularly important for GP services where separate endpoints may be required for direct patient dispositions versus Post Event Messaging (PEM) scenarios.

https://fhir.nhs.uk/England/StructureDefinition/Extension-England-EndpointCompression	draft	0.1.0	2025-07-21	The Endpoint Compression extension is used to signify if the message recipient is able to receive compressed data. This will translate to 'Compressed' or 'Uncompressed' respectively. True indicates 'Compressed' capability, false indicates 'Uncompressed'. Compression reduces bandwidth requirements and can reduce messaging delays and/or failure.	This extension supports the Directory of Service (DoS) use case by enabling systems to determine whether an endpoint can accept compressed data, allowing for optimization of data transmission by reducing bandwidth requirements and potential messaging delays or failures.

https://fhir.nhs.uk/England/StructureDefinition/Extension-England-OrganizationEndpointOrder	draft	0.1.0	2025-07-21	The Organization Endpoint Order extension is used to provide a priority ranking for endpoints associated with an Organization resource, allowing systems to determine the preferred order of endpoint usage.	This extension is a Directory of Service (DoS) use case, Enables prioritization of multiple endpoints for an Organization, supporting scenarios where organizations have multiple communication channels or services that need to be accessed in a specific order of preference.
