Re: [fw-mvc] Zend_Form: dl not output unless a display group is created

Sorry, dumb question...I just looked in the source and found the
information I needed.

I don't want to overwrite the default decorators, but I would like to
add some options to some of them. Is the right way to accomplish this
call addDecorator($decorator, array $options), which will override the
decorator of the same name, but with the new options?
