Use with `where` to narrow further.                                                                       |
-| assertions | [Assertion object](#assertion-object) | **REQUIRED.** Flags a problem when a defined assertion evaluates false. There are a variety of built-in assertions included. You may also create plugins with custom functions and use them as assertions.                                                                                                                             |
-| where      | [Where object](#where-object)         | Narrows subjects by evaluating the where list first in the order defined (from top to bottom). The resolution of reference objects is done at the `where` level. See [where example](#where-example). The `where` evaluation itself does not result in any problems.                                                                   |
-| message    | string                                | Custom text displayed when an assertion fails. Placeholders can be used to include contextual information such as the rule name, object type, property, error location, and problems. See [Using message placeholders](#using-message-placeholders) and [List of available placeholders](#list-of-available-placeholders) for details. |
