The structure of the sentence above is "MUST NOT $z UNLESS $a OR $b". Take it as "MUST NOT <play video games> UNLESS <completed chores> OR <no school tomorrow>". When <no school tomorrow> then this does not say anything about <play video games>. Same when <completed chores>. When you are caught at <play video games> while neither <no school tomorrow> nor <completed chores> however, then that's non-compliant. The Link header is a case of <completed chores>. -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://bjoern.hoehrmann.de Am Badedeich 7 · Telefon: +49(0)160/4415681 · http://www.bjoernsworld.de 25899 Dagebüll · PGP Pub.
