Yes, for the interested the following is a great description of locale\language distinction and it's relative fuzziness:


I think however that the "lang" tag and resolution algorithm is currently more that adequate and takes all the required configuration into account for resolution of declaration and intent.

The 'flip' is already possible by user-preference override which appears to mostly be the default implementation choice in browsers. 

With advancements in data markup and hopefully the universal deferment of presentational rendering into the UA, this would provide consistency for users who want data to be 'flipped' automatically, ie i'm thinking of <input>, <output> and <data> here... the elimination of pre-rendered values is key.

I agree that CSS is a better place for this to be defined and XBL the method for rich interfaces.

Looking forward to some tasty pie flavoured from around the world, or mashed up into a regional taste :)

Quick additional thought, potentially the translate attribute may be used as an additional indicator as to the scope of 'flipping'.
