CSS 2.1 text-transform ambiguity

Hello,

     I am designing a web application for managing accounting data. To prevent 
users from "instinctively" holding SHIFT to capitalize, I am capitalizing all 
text displayed in form elements (input[type='text'] {text-transform: 
uppercase}). This, of course, has no effect on the *actual* data passed to the 
application server.

     This technique works in Gecko and IE, but KHTML (both Konqueror and Safari) 
ignores this CSS property of the <input> tag, presumably because, technically, 
this is not "enclosed" text as the specification seems to point out.

     Perhaps some stipulation should be added to the CSS spec regarding this 
useful property?

regards,
