Hi Maxime,

have you read whole thread regarding its-*?

Especially
http://lists.w3.org/Archives/Public/public-multilingualweb-lt/2012Mar/0005.html

and also HTML WG mailing list

http://lists.w3.org/Archives/Public/public-html/2012Mar/0466.html

We can use such attribute, it will not be valid HTML5 but we can create
applicable specification defining such attributes. Moreover we plan to
change conformance definition of HTML5 in this area.

data-* are not meant for interchange, they are private to particular
application operating on page.

Well, I don't think so.
