ZF-1666: Zend_View - form helpers produce extraneous hidden elements
Several form helpers produce extraneous hidden elements (such as formCheckbox).
If the developer chooses to produce hidden elements, they should do so with formHidden(), having _hidden automatically implied makes for hard-to-debug xhtml / js / form elements.
Furthermore, while not completely sure at the moment, I dont think this meshes well with the future of xhtml, specifically when it comes to the name and id attributes.
More notes later.
