The point is, you **couldn't** get a fieldset **without** a label/legend before that. Now you **always** get a fieldset - either with or without legend depending on whether a label is set for the fieldset. So it's more predictable what you get. And when you set ```Zend\Form\View\Helper\FormCollection::$shouldWrap = true``` I'd expect it to wrap my content up into something and not only because I've also set a label for the Collection.

Agreed, If you see it as a BC-Break, I could add another property containing a default that wraps everything up into nothing (i.e. ```'%s'```) which is used when only ```$shouldWrap``` is set but no label is given. This property can then be set by the user to ```'<fieldset>%2%2%3</fieldset'``` to get the expected behaviour.
