 // There are also these departures from the JSON Schema proposal:
 // - function and undefined types are supported
 // - null counts as 'unspecified' for optional values
 // - added the 'choices' property, to allow specifying a list of possible types

 // - by default an "object" typed schema does not allow additional properties.
 //   if present, "additionalProperties" is to be a schema against which all
