Validation problem

Dear Sir or Madame,

 

I just tried to validate http://www.npc.nato.int/htm/home.htm
<http://www.npc.nato.int/htm/home.htm>  and I got an error message as
follows:

 

1.	Error Line 79 column 85: there is no attribute "autocomplete".

....//www.google.com/u/NPC" autocomplete="Off">
 
 

The attribute and the setting (autocomplete="Off") is however not in my
source file. Is this a bug?

 

Regards,

Leif
