The prose for charGroupPart says it includes charClassEsc, but the production says it includes charClassExpr. If the given production is correct, then we may have regular expressions such as: [[abc]] If that is the case, I think the "changes since 1.0" section should explicitly point it out. As far as I know, such an RE would not be valid under the 1.0 grammar.

Specifically, change charGroupPart ::= singleChar | charRange | charClassExpr to charGroupPart ::= singleChar | charRange | charClassEsc in production 80, the production for charGroupPart.
The WG approved the text in comment #2 as decided.
The change described in comment 2 has now been made in the status quo documents, so I'm marking this issue resolved. The originator of this issue (Kevin Braun) should receive an email notification of this status change. If you are happy with the WG's disposition of your comment, please so indicate by closing the bug report; if something has gone wrong and you're not happy, please reopen it. If we don't hear from you in the next two weeks, we'll assume you are happy with the change being made. Thank you in any case for catching this error.
