Please review it carefully and let us know if you agree with it or not

Your comment on 3.22 STYLE_SHEETS_USE:

Working Group Resolution:
1. editorial
2. we will warn if css rules apply only to screen media type
3. we will clarify that styles that have no media descriptor actually
refer to all, not to screen.
