The JSONiq specification includes adding boolean literals [1] to XQuery to support for JSON. Please create an issue for boolean literals. At this time we can use the XQuery boolean options until we have time to add JSON boolean literals to the code base. The specification talks about a parameter to allow boolean and null interpretation. For now we can consider this property turned off.
