+  <!-- Notes about the values set below:
+    1. For macOS it's possible to sign both the app bundle (EnableCodesigning=true) and the package (*.pkg) (EnablePackageSigning=true),
+       and these are signed separately and with different certificates.
+          CodesignKey: this is the signing key used for the app bundle
+          PackageSigningKey: this is the signing key used for the package
+    2. Publishing to the App Store requires signing both the app bundle and the package.
+          Must be 'Apple Distribution: ...' for the app bundle. Note that apps signed like this will not execute locally.
+          They have to be published to the App Store and then downloaded (Apple will resign the app with a different signing identity that allows for local execution).
+          Must be '3rd Party Mac Developer Installer: ...' for the pkg
+    3. Publishing outside of the App Store (i.e. only notarizing) requires:
+          Must be 'Developer ID Application: ...' for the app bundle
+          Must be 'Developer ID Installer: ...' for the pkg
+    4. During development, use the 'Apple Development: ...' signing key (typically to verify that the app works when is signed and entitlements are enforced).
+    5. Depending on the entitlements the app needs, a specific provisioning profile (CodesignProvision) might be needed.
+    6. UseHardenedRuntime must be set to true when app sandbox is enabled in Info.plist.
