Uni-Form is an attempt to standardize form markup (xhtml) and css, “modularize” it, so even people with only basic knowledge of these technologies can get nice looking, well structured, highly customizable, semantic, accessible and usable forms.
An interesting approach using javascript to give a very nice indicator of where the current focus is. Gives clean mark up and they do look nice. There are some prototype versions of the jquery parts to handle highliting the elements as they get focus. Seems to have a nice semantic nature. Would be easy to build a version of the formHelper for cakephp to help make use of this down the road.
