I would not object to that, but I can't speak for Chet. Another option would be to refer to the POSIX definition of Extended Regular Expressions as a web site. I wish they had better URLs, though. The URL I have for it at the moment is http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html#tag_09_04
