Whoopsy, left a bit of code out of my above solution that caused Simple CMS pages to fail :

class Category extends \XLite\View\AView 
{
        // add this in
	public static function getAllowedTargets()
	{
		$result = parent::getAllowedTargets();
		$result[] = 'category';
		$result[] = 'main';
		return $result;
	}
