description: A profile on the mCSD Endpoint for Document Sharing environments.\n\nGiven that in FHIR R4 the .connnectionType is 1..1, each type of endpoint will be indicated with an independent Endpoint resource. Thus a XCA Responding Gateway will need two Endpoint instances to express Query vs Retrieve.\n\nOpen-Issues:\n1. That payloadType and payloadMimeType are either empty to indicate that the endpoint is not constrained; or fully populated. \n2. That payloadType and PayloadMimeType for XCA/XDS/MHD Query and XCA/XDS/MHD Retrieve would be the same thus replicating the capability at both endpoints. \n3. It did not seem right that Query be indicated with a mimeType of ebRegistry as that is not helpful to the use-case.\n4. should the homeCommunityId be mandated here, should those behind it be here, should this be empty?\n5. would a Proxy service that is supporting OrgAff be a good example of NOT putting a homeCommunityId in the endpoint.identifier? package_name: ihe.iti.mcsd derivation: constraint name: MCSDEndpointDocShare type: Endpoint elements: extension: index: 0 slicing: rules: open ordered: false discriminator: - {path: url, type: value} min: null slices: specificType: match: {url: null} schema: {type: Extension, mustSupport: true, url: 'https://profiles.ihe.net/ITI/mCSD/StructureDefinition/ihe-endpointspecifictype', index: 1} min: 0 identifier: {short: should be the homeCommunityId(s), index: 2} connectionType: binding: {strength: required, valueSet: 'https://profiles.ihe.net/ITI/mCSD/ValueSet/MCSDEndpointTypesCoreDocShareVS'} index: 3 name: {short: Nothing useful to put in the name, index: 4} payloadType: {short: FormatCode(s), mustSupport: true, index: 5} payloadMimeType: {mustSupport: true, index: 6} address: {index: 7} header: {short: XCA defines protocol, index: 8} package_version: 3.6.1 extensions: specificType: {url: 'https://profiles.ihe.net/ITI/mCSD/StructureDefinition/ihe-endpointspecifictype', min: 0, type: Extension, mustSupport: true, index: 1} class: profile kind: resource url: https://profiles.ihe.net/ITI/mCSD/StructureDefinition/IHE.mCSD.Endpoint.DocShare base: https://profiles.ihe.net/ITI/mCSD/StructureDefinition/IHE.mCSD.Endpoint version: 3.6.1
