- <input type=input name=x value=y>
- <input type=radio name=x value=y>
- <option value=x>
value
attribute must be present. additional information is provided below.If the enclosing <form> tag has the attribute "prepend", then "prepend" is tacked on the front of each variable name before its value is looked-up. The "prepend" attribute is then removed from the form tag.
