Yes. A media-type is a major-type / minor-type plus an optional list
of parameters which are separated from themselves and the major/minor
type info by semi-colons, eg:
text/plain; charset=utf-8; otherparam=xxx; q=0.5

No quality specifier indicates priority 1.0 (the highest).

My original was cut straight out of rfc2616 and is formatted badly (I
think to empahsise the syntax over any arbritary textual ordering).
A more sensible textual rendering would look like this:
Accept: text/plain; q=0.5,
text/html; q=1.0,
text/x-dvi; q=0.8,
text/x-c; q=1.0
Hope that's clearer.
