RFC 2616 errata: invalid language tag "x-pig-latin"

Hello,

just a minor error:
In RFC 2616 chapter 3.10 "Language tags", there is the text:

"Example tags include:

en, en-US, en-cockney, i-cherokee, x-pig-latin"

However, the language tag "x-pig-latin" is invalid because the subtag is
more than 8 characters long and contains a "-" (only ALPHA is allowed).

Please CC me in replies to the HTTP WG list as I am not subscribed.

Regards,
