Attribute for <BUTTON ...>
TYPE =BUTTON |SUBMIT |RESET

TYPE indicates that the button is one of three types:

• BUTTON (the default) creates a button in the same way <INPUT TYPE=BUTTON> does. A button of this type requires a script for it to do anything.
• SUBMIT creates a submit button like <INPUT TYPE=SUBMIT>
• RESET creates a submit button like <INPUT TYPE=RESET>
