Re: The underscore

Hi,

Section 4.1.3 of CSS Level 2 contains the paragraph

  In CSS2, identifiers (including element names, classes, and IDs in
  selectors) can contain only the characters [A-Za-z0-9] and ISO 10646
  characters 161 and higher, plus the hyphen (-); they cannot start with
  a hyphen or a digit. [...]

The errata proposes a change for section 4.1.1 and appendix D but omits
the mentioned section.
