page errors at w3 site

  Hello,

  please be advised that the W3C validator, as accessed from iCab's  
contextual
  menu, reports errors on the pages
       http://www.w3.org/2008/site/css/minimum
       and
       http://www.w3.org/2008/site/css/advanced

  I actually thought at first that iCab's error report must be wrong,  
before I ran
  the validator.  I should have known better.


  Thank you.
