   • Integrated SimulationResourceMetaData.xsd schema for SRMD validation.

2. Schema Updates:

   • Replaced xs:dateTimeStamp with a custom dateTimeStampType in SSPTraceabilityCommon.xsd for compatibility with XML Schema 1.0.

3. Testing:

I believe that everything is okay with merging this part. Other than changing the SRMD sample that could be another issue and it's not related to this issue for now.
