There are other ways to denote required fields, and the approaches
differ from developer to developer and site to site. Right now, the
label is marked with a class of "required" when the element is required,
allowing CSS styling. You can change that behavior, as well as prefix or
suffix either optional or required elements; it's all configurable.

You can configure the label decorators at any time by pulling them from
the individual elements, or simply configure them at element
instantiation (which, unfortunately, requires that you configure all
decorators).

Also, as noted, if you have a default behavior you want for *your*
forms, you can extend the default label decorator to specify your
desired behavior:

class My_Decorator_Label extends Zend_Form_Decorator_Label
{
public function __construct($options = null)
{
$this->setOption('escape', true)
->setOption('requiredSuffix', ' <span>*</span>');
parent::__construct($options);
}
}

Then, simply ensure your form specifies an appropriate element prefix
path:

$form->setElementPrefixPath('My_Decorator', 'My/Decorator', 'decorator');

(This must be done prior to creating any elements.)
