+## Suppression
+``` yaml
+directive:
+  - suppress: RequiredPropertiesMissingInResourceModel
+    from: networkwatcher.json
+    where: $.definitions.PacketCaptureResult
+    reason: Packet capture is a non tracked child resource. It has 'name' and 'id' but does not have a 'type'
+  - suppress: RequiredPropertiesMissingInResourceModel
+    from: networkwatcher.json
+    where: $.definitions.NetworkWatcher
+    reason: Network watcher has reference on resource in network.json which contain 'name, 'id' and 'type'
+  - suppress: DefinitionsPropertiesNamesCamelCase
+    from: networkwatcher.json
+    where: $.definitions.ProtocolConfiguration.properties.HTTPConfiguration
+    reason: Accidentally shipped with wrong casing – however fixing the casing is introducing a breaking change which is worse than living with the naming violation
