Hi @Brunoga-MS, the overall direction seems promising.

I recommend dividing the PolicyItems into Assignments and Definitions. Additionally, in the event of a breaking change update, it would be beneficial to support removal on a per-assignment basis, thereby removing only the impacted assignment(s).

Let's update the documentation to incorporate the new script. Also, consider how this approach could assist in streamlining the update documentation.

@arjenhuitema done .. I also make a pass through Acrolinx. I just couldn't test the rendering since looks like HUGO is not working because of something wrong with D:\Sviluppo\azure-monitor-baseline-alerts\services\AVS\privateClouds_index.md:7:1 and "D:\Sviluppo\azure-monitor-baseline-alerts\docs\layouts\partials\templates\template-tabs.html
