-		 *
-		 * Array keys for sections added by core are all prefixed with `wp-`. Plugins and themes

-		 *
-		 *         @type string $label       Required. The title for this section of the debug output.

-		 *                                   may contain basic HTML markup, inline tags only as it is
-		 *                                   outputted in a paragraph.
