Core features include 'title', 1728 * 'editor', 'comments', 'revisions', 'trackbacks', 'author', 'excerpt', 1729 * 'page-attributes', 'thumbnail', 'custom-fields', and 'post-formats'. 1730 * Additionally, the 'revisions' feature dictates whether the post type 1731 * will store revisions, the 'autosave' feature dictates whether the post type 1732 * will be autosaved, and the 'comments' feature dictates whether the 1733 * comments count will show on the edit screen. For backward compatibility reasons, 1734 * adding 'editor' support implies 'autosave' support too. A feature can also be 1735 * specified as an array of arguments to provide additional information 1736 * about supporting that feature. 1737 * Example: `array( 'my_feature', array( 'field' => 'value' ) )`. 1738 * If false, no features will be added. 1739 * Default is an array containing 'title' and 'editor'. 1740 * @type callable $register_meta_box_cb Provide a callback function that sets up the meta boxes for the 1741 * edit form.

To prevent rewrite, set to false. 1752 * Defaults to true, using $post_type as slug. To specify rewrite rules, an array can be 1753 * passed with any of these keys: 1754 * 1755 * @type string $slug Customize the permastruct slug.

Otherwise posts are not trashed or deleted. 1777 * Default null. 1778 * @type array $template Array of blocks to use as the default initial state for an editor 1779 * session. Each item should be an array containing block name and 1780 * optional attributes. Default empty array. 1781 * @type string|false $template_lock Whether the block template should be locked if $template is set. 1782 * * If set to 'all', the user is unable to insert new blocks, 1783 * move existing blocks and delete blocks. 1784 * * If set to 'insert', the user is able to move existing blocks 1785 * but is unable to insert new blocks and delete blocks. 1786 * Default false. 1787 * @type bool $_builtin FOR INTERNAL USE ONLY!
