When I say "hidden", I do not neccesarily mean "unaccessible". I can think 
of many ways to provide a policy or something that would determine which 
normalization form would be used on a call to the == operator. My point was 
that we should not require the common user to know what a normalization form 
is, and to aid that provide a default normalization policy that maps the 
closest to "common sense". ('ö' should "equal" 'o¨' for example.)
