If you are referring to the fact that normalization of the user name part of the UPN hint is not fully defined, that does not make this specification un-implementable. Anny client/server based system that currently is using TLS for user authentication must have an understanding of how names they use to access accounts are formed. This standard makes it possible for them to send that username in that form. If we enforce specific character normalization on the user name then they may not be able to use this standard anymore as it may conflict with how they encode usernames. Many standards define fields that higher level protocols and apps can use in multiple ways. That does not make those standards un-implementable. It's just a limitation of scope. > > > >S 4: > > >You can do the UPN hint extension exchange and then NOT > > >send supp_data?
