[MOBY-l] Boolean object

[Gary Schiltz]

I think I'm in Paul's camp here, although I notice that the W3C 
recommendation on XML Schema allows true, false, 1, and 0 as valid 
lexical values for booleans (see www.w3.org/TR/xmlschema-2/#boolean). 
But then, they say that the "canonical representation" for booleans is 
true and false. I am still confused as to the difference between the 
lexical and canonical representations.
