// to which it serializes it's input value, so that form submission (either normal submission or via FormBind?)
// works as expected.
// Don't attempt to mixin the 'type', 'name' attributes here programatically -- they must be declared
// directly in the template as read by the parser in order to function. IE is known to specifically
// require the 'name' attribute at element creation time. See #8484, #8660.
