	//		that have user changeable values.
	// description:
	//		Each _FormValueWidget represents a single input value, and has a (possibly hidden) `<input>` element,
	//		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.
