I've copied this to the HTML list since it's more on-topic there.

Yeah, you just use a comer separated list, it's in the rfc.

Are you sure?

I assumed that when the language was specified in a higher protocol it
would over rule the language set in the document.

This is how it works with char sets -- see the latest XHTML 1.0 draft

  An XML declaration ... is required when the character encoding of the
  document is other than the default UTF-8 or UTF-16 and no encoding was
  determined by a higher-level protocol.

this was changed from the last version [2] because HTTP takes
precedence over (X)HTML because it's a higher level protocol.

I assumed that the same thing applied to language.
