x1 and x2 are elements of the same partially-ordered set x3 (see notes) such that x1 and x2 cannot be meaningfully compared via said relation/in said property.
Neither is more nor less than the other because those relations/concepts simply do not make sense for the given pair. x3 accepts sumti of either of two types/structures: (1) a partially-ordered set in which both the underlying set and the order relation on it are specified explicitly (see: "cmacistura"); (2) a simple "ka" construct indicating a property or characteristic which roughly functions as the basis of an assumed partial-order relation on an unspecified or vague partially-ordered set, in a fashion which is grammatically approximately analogous to "zmadu"'s structure.
