It has been changed to "their", but that doesn't help you much.
I'm not exactly sure what to do here, so I'm asking the mailing list.

The EB announces the existence of both:

It's out as -11.

BTW: actually the registry is called: "IEEE Std 802.15.4 IETF IE Subtype IDs".
I wonder if it should have been expanded in the registry :-)
