NonEmptyClassRangesNoDash production cannot specify a multi-character set
|
|
("B" parameter)

info: |
|
|
The production
|
|
NonemptyClassRangesNoDash::ClassAtomNoDash-ClassAtomClassRanges evaluates
|
|
as follows:
|
|
|
|
1. Evaluate ClassAtomNoDash to obtain a CharSet A.
|
|
2. Evaluate ClassAtom to obtain a CharSet B.
|
|
3. Evaluate ClassRanges to obtain a CharSet C.
|
|
4. Call CharacterRange(A, B) and let D be the resulting CharSet.

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

The `u` flag precludes the Annex B extension that enables this pattern.
