Re: [xml-dev] Constraining XML instances using standard logic properties

I have a sibling, Matt, and another sibling Erika.  They are not siblings.

(True story: I share a different parent with each).

I guess the moral is that you need to be careful about assuming that these properties are fundamental and universally true, or if they depend on some other context or definition...

if(anything) then true() else false()

can be more simply written as

anything

or boolean(anything) if it isn't already a boolean expression.
