Introduction - Understanding and Using Zend Form Decorators
Zend_Form utilizes the decorator pattern in order to render elements and forms. Unlike the classic » decorator pattern, in which you pass an object to a wrapping class, decorators in Zend_Form implement a » strategy pattern, and utilize the metadata contained in an element or form in order to create a representation of it
