Cookie Directive and HTML5

Are  there  mechanisms  in  html5  that  have  no  privacy  concerns,  yet  is  subject  to  the  consent requirement?  A  browser  supporting  offline  applications  will  download  all  these  resources  so  that that the application works even if there’s no internet connection. Note that if the browser does not support offline apps, they still work – they just require you to be online. This mechanism causes the storing  of  information  on  the  end  user  computer.  This  storage  is  not  strictly  necessary  in  order  to provide the service. No information is ever accessed by the provider of the website, but this is not a requirement  of  the  directive,  storing  of  information  is  enough.  Thus,  consent  is  needed.  And  yet there are no privacy concerns.
