If you do an <input type=number>, most newer browsers will restrict values to \
numeric, mobile browsers will pop up a numeric keypad, and old browsers will just do \
a normal text field because they don't recognize that type (and the default is plain \
text). You can't rely on that (always verify on the server side), and the ui_lib \
doesn't create these for you, but giving some feedback on the client side this way is \
almost free, so it's basically win-win. :)
