I believe that when you restrict a schema type to eliminate a canonical 
form, then the resulting type has no canonical form for the value(s) in 
question.  I >think< but am not 100% sure that attributes of the 
restricted type cannot have default or fixed values (which must be valid 
per the canonical type).

Well, the canonical rep for xs:boolean is false, but this isn't 
xs:boolean, it's a type that only allows the lexical reps '1' and '0', so 
I'm not certain that rule applies...

I'll check with the XML Schema WG.
