It's true if you mean Schema 1.1 Part 2, located here: http://www.w3.org/TR/xmlschema11-2/#language But XHTML M12N (shudder, another numeronym) references RFC 3066 directly (and not BCP 47) and XML Schema 1.0. These are only references to BCP 47 insofar as RFC 3066 used to be BCP 47. Addison Addison Phillips Chair -- W3C Internationalization WG Editor -- IETF LTRU WG (BCP 47) Internationalization is not a feature. It is an architecture.
