It refers to markup, and this in practice can only mean <meta> tags.

This does not violate checkpoint 7.5, since the server performs the
redirect. There are other aspects, though, like sending 302 instead of
301, but this is mainly an efficiency issue (the browser is required to
keep using the default.asp address instead of optimizing further
references) and, more importantly, not using automated language
negotiation, which is a fairly advanced topic but worth a look in a
bilingual country, see http://www.cs.tut.fi/~jkorpela/multi/
(but this is just marginally related to accessibility).
