Is the discriminant value always a constant? Perhaps DWARF should say, "The value of this attribute is of class constant." Table 2.3 defines attribute class constant as, "One, two, four, eight or sixteen bytes of uninterpreted data, or data encoded in the variable length format known as LEB128 (see Section 7.6 on page 221).".
