     * Checks whether this object is of type {@link module:engine/view/node~Node} or its subclass.
     *
     * This method is useful when processing view objects that are of unknown type. For example, a function
     * may return a {@link module:engine/view/documentfragment~DocumentFragment} or a {@link module:engine/view/node~Node}
     * that can be either a text node or an element. This method can be used to check what kind of object is returned.
     *
     * ```ts
     * someObject.is( 'element' ); // -> true if this is an element
     * someObject.is( 'node' ); // -> true if this is a node (a text node or an element)
     * someObject.is( 'documentFragment' ); // -> true if this is a document fragment
     * ```
     *
     * Since this method is also available on a range of model objects, you can prefix the type of the object with
     * `model:` or `view:` to check, for example, if this is the model's or view's element:
     *
     * ```ts
     * viewElement.is( 'view:element' ); // -> true
     * viewElement.is( 'model:element' ); // -> false
     * ```
     *
     * By using this method it is also possible to check a name of an element:
     *
     * ```ts
     * imgElement.is( 'element', 'img' ); // -> true
     * imgElement.is( 'view:element', 'img' ); // -> same as above, but more precise
