MMC XSD comparison

Sub-GHz configuration, scan and channel responses

Adds the MMC output types for the CHF Sub-GHz services: SetCHFSubGHzConfigurationRsp, RequestCHFSubGHzChannelScanRsp, ReadCHFSubGHzConfigurationRsp, ReadCHFSubGHzChannelRsp and ReadCHFSubGHzChannelLogRsp, together with the CHFSubGHzChannelLogEntry rows they carry. ResponsePayload offers each of them as a new SMETSData choice.

Device log entries report Sub-GHz link quality

CHFDeviceLogEntry gains an optional SubGHzLinkQuality element, an xs:short constrained to -128 to 127, reported after the existing DeviceID and LastCommunicationsDateTime.

Counter-reset and event/alert behaviour responses

Adds UpdateDeviceConfigurationDailyResettingOfTariffBlockCounterMatrixRsp and UpdateDeviceConfigurationRMSVoltageCounterResetRsp, plus ReadDeviceConfigurationEventAndAlertBehavioursRsp with the ElectricitySupplierAlertsEvents and ElectricityNetworkOperatorAlertsEvents groups that carry the per-alert behaviour settings.

Smart Meter Integrity Issue Warning alert

DeviceAlertMessagePayload gains a SmartMeterIntegrityIssueWarningDeviceAlert choice, defined by the new SmartMeterIntegrityIssueWarningDeviceAlertType.

Credential exchange status values revised

StatusASN1 removes contingencyPublicKeyDecrypt and adds noCBKEResponse and noPartnerLinkKeyReceived, so the reported outcome distinguishes a missing CBKE response from a missing partner link key.

Response schema version pinned to 2.0

The GBCSResponse schemaVersion attribute changes its fixed value from 1.0 to 2.0.

The schema no longer imports DUIS

MMC 1.0 and 2.0 imported the DUIS ServiceUserGateway namespace and referenced its types with an sr: prefix. From 3.0 the xs:import is removed and those 71 types are declared locally in the ResponseAndAlert namespace instead. That is why this release shows by far the largest component count in the comparison: 49 existing types are listed as changed only because a type reference moved from sr: to ra:, with no change to the data they carry. The moved definitions match the ones DUIS declares at the same release.

SMETS1 responses gain their own status and debug types

Adds StatusSMETS1 and SMETS1DebugType, the only two declarations in this release that are new rather than moved from DUIS. ResponsePayload offers SMETS1Debug as a new DebugInfo choice, so a countersigned SMETS1 response can carry SMETS1-specific diagnostic content.

Header message code becomes optional

HeaderType/GBCSHexadecimalMessageCode changes from mandatory to minOccurs="0", so a response header need not carry a GBCS message code. Its remaining changes are sr: to ra: retyping of BusinessOriginatorID, BusinessTargetID, SupplementaryRemotePartyID, ServiceReference and ServiceReferenceVariant.

Device alert code becomes optional

DeviceAlertContentType/GBCSHexAlertCode changes from mandatory to minOccurs="0".

Debt recovery periods narrowed

ElecDebtRecovery/DebtRecoveryRatePeriod removes WEEKLY, MONTHLY and QUARTERLY, leaving HOURLY and DAILY. This matches the same narrowing made on the DUIS request side.

Non-disablement schedules use wildcard-free dates

ElectricityNonDisablementSchedule/ScheduleDatesAndTime is retyped to the new ScheduleDatesAndTimeWithoutWildcards. The original ScheduleDatesAndTime now requires StartDate and EndDate and types them as ra:Date rather than xs:date.

Response schema version no longer fixed

The GBCSResponse schemaVersion attribute drops its fixed value, so the attribute is still required but is no longer pinned to one release in the schema.
