Return true if the specified year and dayOfYear represents a valid date value, and false otherwise. Note that valid date values are (as fully defined in the component-level documentation) in the range [ 0001/01 .. 9999/365 ] (except that [ 1752/356 .. 1752/366 ] are not valid for historical reasons).
