-* `included_applications` - (Optional) A list of application IDs the policy applies to, unless explicitly excluded (in `excluded_applications`). Can also be set to `All`, `None` or `Office365`. Cannot be specified with `included_user_actions`. One of `included_applications` or `included_user_actions` must be specified.
-* `included_user_actions` - (Optional) A list of user actions to include. Supported values are `urn:user:registerdevice` and `urn:user:registersecurityinfo`. Cannot be specified with `included_applications`. One of `included_applications` or `included_user_actions` must be specified.
+* `filter` - (Optional) A `filter` block as described below.
