if the language markup is page specific, and with the geographic targeting potential that is attached with it, why isn't it more often used...... i mean, why in a non subdomain site, different pages are not targeted according to different languages more often?... dont u think it is a cleverer idea compared to creating an independent subdomain for every region/country/ language?

what could be merits and demerits of this approach?
