"en_US" or "en-US" is really a question of style. "en_US" is POSIX
locale style, and "en-US" is RFC 1766 style. Since, AFAIK, TDG
doesn't mention RFC 1766 or xml:lang (which follows RFC 1766 style and
which, by this time, many people are familiar with), there's nothing
to say that "en_US" is wrong.
RFC 1766 was published in March 1995. I don't remember when the lang
attribute was added to DocBook, but I expect that it was long before
1995. That, plus DocBook's origins as software documentation and the
existence of the "en_US" example in the definitive guide, seems in
indicate that "en_US" is more right than it is wrong.
OTOH, DocBook in XML that uses xml:lang instead of lang should use RFC
1766 style in the xml:lang attributes.
