The following conformanceUnits exist for standard roles

• Security Role Well Known - Support the well-known Roles "ConfigureAdmin" and "SecurityAdmin" with suggested permissions defined in UA Parts "AddressSpace Model" and "Role Based Security"
• Security Role Well Known Group 2 - Support the well-known Roles "Anonymous" and "AuthenticatedUser" with suggested permissions defined in UA Parts "AddressSpace Model" and "Role-Based Security".
• Security Role Well Known Group 3 - Support the well-known Roles "Observer", “Engineer”, “Supervisor”, and "Operator" with suggested permissions defined in UA Parts "AddressSpace Model" and "Role-Based Security".

The first one is mandatory in User Role Management 2022 Server Facet, the other two are optional.

During the UA meeting it was suggested that Anonymous shoudl also be mandatory (moved into the first group) and that each of the other should be in there own optional conformanceUnit (so a vendor can should with of the optional item they actually support). - i.e. one for Observer, one for Engineer...

Once ConformanceUnits are created, Part 18 might also need to be updated - since it does list the ConformanceUnits.
