Fwd: clarify boolean

Hello,

throughout the spec, there are references to the use of boolean
values, can we explicitly clarify these e.g. as xs:boolean.

for example, in

7.1.3 p:compare

it says;

----

The value of the fail-if-not-equal option must be a boolean.

----

should we not say xs:boolean (to cover 0 and 1 and true, false)

might want to take a look at XML Query 2.4.3 Effective Boolean Value
section for some background reference

cheers, Jim Fuller
