 * Hello, the [w3c tool to validate online documents](http://validator.w3.org/) 
   now remove the profile, canonical and others attributes.
    The attributes now 
   supported are here ( [http://www.w3schools.com/html5/tag_link.asp](http://www.w3schools.com/html5/tag_link.asp)).
   Also the default Twenty Ten theme use html 5 with those attributes, now to make
   a valid w3c page I need to wait new html 5 specifications ?

 * You can still validate against other specification, like “HTML 4.01 Strict” or“
   XHTML 1.0 Transitional”. You don’t have to validate against HTML 5.

 * To validate against HTML 5 you may have to modify themes, but you don’t have 
   to validate against HTML 5. I don’t know what the question is at this point.

 * My question is: where I can find a documentation to substitute invalid and deprecated
   attributes, the online documentation still learn invalid attributes (like microformats
   wiki).
 * At this time I follow your solution, switch html5 templates to xhtml 1.0 transitional…

 * About 90% of the I just validate and fix, though. I pick up the difference pretty
   quick that way.
