Sure it does, as you quote below -- "as defined in Attribute Wildcard Intersection", which in turn says "For a wildcard's {namespace constraint} value to be the intensional intersection of two other such values . . .", which is a definition of 'intensional intersection'. > Can someone tell me what they mean? <snip/> > What if the above had just said ".. is the intersection of the ...". > Would this sentence mean anything different? Sure -- it would be incoherent -- intersection as such is an operation on sets. A wildcard definition isn't a set, it's a characteristic function for a (possibly infinite) set. By 'intensional' I mean that the operation is defined at the characteristic function == descriptive level, not the set level itself. ht -- Henry S.
