     11    The production
     12    NonemptyClassRangesNoDash::ClassAtomNoDash-ClassAtomClassRanges evaluates
     13    as follows:
     14 
     15    1. Evaluate ClassAtomNoDash to obtain a CharSet A.
     16    2. Evaluate ClassAtom to obtain a CharSet B.
     17    3. Evaluate ClassRanges to obtain a CharSet C.
     18    4. Call CharacterRange(A, B) and let D be the resulting CharSet.

     22    1. If A does not contain exactly one character or B does not contain
     23       exactly one character, throw a SyntaxError exception.
