XSD 1.0 Datatypes Appendix F defines SingleCharNoEsc as [^\[\]] and admits a nested class only as a -[...] subtraction, so a `[` inside a character class that is not introduced by `-` is a syntax error. RegexParser treated such a `[` as a literal scalar, so `[a[:xyz:]` compiled and the schema declaring it was wrongly accepted (XSTS RegexTest_993, RegexTest_1477). nextClassMember now throws a dedicated RegexError.unescapedClassBracket, kept distinct from the generic, deliberately-lenient badClass so the change cannot regress a valid-but-unsupported pattern. XSDSimpleParser.rejectsPattern treats it as a genuine syntax error, so the declaring schema is invalid. Closes RegexTest_993 and RegexTest_1477: invalid-schemas-accepted 15 -> 13, valid-schemas-rejected held at 0, instance buckets unchanged (full XSTS archive). Escaped [a\[c] and subtraction [a-z-[aeiou]] stay valid; the unterminated case [a[:xyz: now faults on the inner [. |
