unrestricted double	valueAsNumber
double	valueHigh
double	valueLow

boolean	willValidate The willValidate attribute must return true if an element is a candidate for constraint validation, and false otherwise (i.e. false if any conditions are barring it from constraint validation).

Operations
boolean	checkValidity() When the checkValidity() method is invoked, if the element is a candidate for constraint validation and does not satisfy its constraints, the user agent must fire a simple event named invalid that is cancelable (but in this case has no default action) at the element and return false.
boolean	reportValidity() When the reportValidity() method is invoked, if the element is a candidate for constraint validation and does not satisfy its constraints, the user agent must: fire a simple event named invalid that is cancelable at the element, and if that event is not canceled, report the problems with the constraints of that element to the user; then, return false.
void	select() The select() method must cause the contents of the text field to be fully selected, with the selection direction being none, if the platform support selections with the direction none, or otherwise forward. The user agent must then queue a task to fire a simple event that bubbles named select at the element, using the user interaction task source as the task source.
void	setCustomValidity(DOMString error) The setCustomValidity(message), when invoked, must set the custom validity error message to the value of the given message argument.
void	setRangeText(DOMString replacement, optional unsigned long start, optional unsigned long end, optional SelectionMode selectionMode)
void	setSelectionRange(unsigned long start, unsigned long end, optional DOMString direction) The setSelectionRange(start, end, direction) method must set the selection of the text field to the sequence of characters starting with the character at the startth position (in logical order) and ending with the character at the (end-1)th position. Arguments greater than the length of the value of the text field must be treated as pointing at the end of the text field.

void	stepUp(optional long n)
