The site doesn't rely on the UA providing a nice UI, but by setting  
these attributes it allows a UA that *can* provide an enhanced user  
experience to do so.  For instance type=search does not have to do  
anything, but on UAs that support it, it can maintain things like  
search history or whatnot.

There is also the potential for these attributes to allow improved  
support for accessibility or input methods.
