In the current IETF/IANA language tag registry
<http://www.langtag.net/registries.html>, kho (Khotanese) exists but
there is no code xsk.

In the future version (the successor of today's RFC 4646, which will
be the first one to incorporate ISO 639-3), there will be a xsk for
Sakan. See
<http://www.sil.org/iso639-3/documentation.asp?id=xsk>

Now, are there the same language or not? Currently, ISO 639-3
registration authority says no... And we follow them.
