OK, so I guess that's what RFC 4646 suggests de-1996 for -- I suppose
the reform was first introduced in 1996 and adopted only later? See
ftp://ftp.rfc-editor.org/in-notes/rfc4646.txt, page 13 (Mojca, the
preceding paragraph is for you ;-)

Maybe; we've now the 42th reform of the reform - a lot is back to pre-reform orthography (or both styles are allowed).

2005 was only a estimation - AFAIR in 2005 the reformed orthography became standard for schools and public authorities.
