| 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. |
| |
| 21.2.2.15.1 Runtime Semantics: CharacterRange Abstract Operation |
| |
| 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. |
