Leave issue open until MSC.530(106) implementation details are finalised (currently in discussions with the ENCWG).
Below is the latest A&I mapping table for references to existing Alert Highlight'' VGs

3 weeks ago My Proposal:
Note: My understanding is that the ENCWG change proposal is not looking at changes to VGs for managing of A&I. This would be an S101 specific implementation (an enhancement to get us closer to MSC.530 requirements).
Functionality: By switching the 'Alerts Highlights' VG layers OFF, mariners won't get an A&I when their 'safety framework' in Route Planning or Monitoring clashes with the corresponding feature/attribute combinations as listed in https://github.com/S-101-Portrayal-subWG/Working-Documents/files/15241188/S-101.Alerts.Mapping.Table.v10.20240507.xlsx. This means no yellow/red highlight, sound or entry in the Alerts Panel. This is under the premise that the mariner wants to reduce 'Alerts fatigue' and wants to prioritize his attention to certain elements only (depending on his area of operation, time of the day, etc). A permanent indication that some A&I have been disabled should be presented on the ECDIS screen and the actions of the mariner (switching Alerts VG layers ON/OFF) appropriately recorded in the ECDIS log (who/what/when).

IHO interpretation of requirements is that there is only one user-selectable category for NavHazards, which is supported by the current implementation.
Some changes were done to remove the Alert highlights from VGL and treat them as Independent Mariners' selctors not linked to ECDIS Display Modes, etc @DavidGrant-NIWC -Need confirmation of any PC changes done during the meeting
Refer to https://github.com/iho-ohi/S-164-Sub-Group/issues/88 regarding the impact the deselection of Alerts highlights would have on the entries reported in an ECDIS Alerts panel.

2 weeks ago Implemented by PC 414
NOTE:
The toggles for the graphical highlights are not implemented as Independent Mariner Selectors. All of the current IMS are implemented as viewing group layers. The layers aren't tied to a display mode. Each layer toggles one or more viewing groups. I expect that the ECDIS will expose the IMS selectors to the user. For instance, the IMS for Accuracy toggles viewing groups 90010 (accuracy) and 90011 (the low accuracy symbol).
Since Hannu indicated the alert highlights should not be exposed to the user these are now only provided using viewing groups. The viewing groups are not included in any viewing group layer or display mode. I expect that the ECDIS will not directly expose these viewing group selectors to the user but will instead tie their operation to existing GUI components of the ECDIS.

Also related to https://github.com/iho-ohi/98-interoperability/issues/33
User-selectable object categories need to be created for the navigational hazards alerts. Each category requires a separate viewing group which will be associated with the corresponding alert highlight. Alerts associated with prohibited areas/areas with special conditions already provide user-selectable categories corresponding to viewing groups 53012-53024.
Note that there are only five unused viewing groups available in the 53010-53029 block currently being used for alert highlights. We may need to also use values from 53001-53009 if more than five user-selectable categories are added.
