The header's value is a comma separated list of elements, where each one
can contain parameters separated by semicolons. The "q" parameter
defaults to 1 if absent.
Accept = "Accept" ":"
#( media-range [ accept-params ] )
media-range = ( "*/*"
| ( type "/" "*" )
| ( type "/" subtype )
) *( ";" parameter )
accept-params = ";" "q" "=" qvalue *( accept-extension )
accept-extension = ";" token [ "=" ( token | quoted-string ) ]

Close.
Accept: text/plain; q=0.5,
text/html ; q=1,
