No, that's not quite right. We offer a limited API. You can use all the
publicly available methods. Everything else may change at a later time.

Take a closer look at the code. Place a marker ###MY_CUSTOM_MARKER###
into your template file and set it's content within the hook using
setMarker('MY_CUSTOM_MARKER', $content).

function modifySingleView(tx_seminars_pi1 $parent) {
	$content = 'I\'m your custom marker content.';
	$parent->setMarker('my_custom_marker', $content);
}
