Ready.

This document extends MIME with the capability of supporting sending  one message that contains multiple language versions of the same information. Translations are identified by a language tag and selected by the email client based on a user's language settings.

The document belongs to the application space and there are no direct implications for the operators of networks. An RFC 5706 review does not apply. The document is Ready from an operational and manageability point of view. Some information or references about possible errors and how application debugging is performed in cases of errors would have been useful - I suppose that such information may be included in other MIME documents.
