Underscore (officially "low line", U+005F) is perfectly valid in class
name selectors when properly escaped.  Thus I could match elements in
the class my_class with the valid selector {.my\_class} (note that the
brackets are delimiters for the prose, not part of the selector).

According to Bert Bos, it was an oversight.  For the record read his
message, "Re: Is there a way..." (11 April 2001;

I heard that the World Wide Web Consortium makes its technical
reports, corrections to technical reports, and mailing list archives
consistently available to anyone, anywhere on the Web, free of charge.
 As these materials include the normative, complete CSS
 specifications, you might want to check them:
