Language spec documents prohibited field modifiers

Section 5.6 "Fields" indicates that the modifiers 'atomic', 'final' and 'native' are allowed. However trying to compile a class where any field is marked with these modifiers generates the error:
"atomic|final|native" is not a valid field modifier
It may also be necessary to modify the grammar (S20 - 66) as the list of allowable modifiers is different for fields and methods.
