If specified as a string, the query * ?{query_var_string}={post_slug} will be valid. * @type bool $can_export Whether to allow this post type to be exported. Default true. * @type bool $delete_with_user Whether to delete posts of this type when deleting a user. * * If true, posts of this type belonging to the user will be moved * to Trash when the user is deleted. * * If false, posts of this type belonging to the user will *not* * be trashed or deleted. * * If not set (the default), posts are trashed if post type supports * the 'author' feature. Otherwise posts are not trashed or deleted. * Default null. * @type array $template Array of blocks to use as the default initial state for an editor * session.
