suspect

Reference or replicate part of IEC 61850-7-2 Annex D and table D.1
D.1 Relation of the detailed quality identifiers with invalid or questionable quality

The reason for an invalid or questionable value of an attribute may be specified in more detail
with further quality identifiers. If one of these identifiers is set then validity shall be set to invalid
or questionable.

Decision

16-Sep-2024 Joint TF Hybrid Meeting - Minneapolis:

Reviewed together.

Action Item: Alex and Tom to check the issues and see what are low hanging fruits that can be easily fixed and which of the items will be followed up in the new TF subteam on the topic and which issues are to be assigned to CIM19
