      8    NonEmptyClassRangesNoDash production cannot specify a multi-character set

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

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