Why is a space allowed *after* the semicolon (as in cmpilato's example)?

The definition of 'parameter' doesn't seem to allow whitespace:

   content := "Content-Type" ":" type "/" subtype *(";" parameter)
   parameter := attribute "=" value
   attribute := token ; case-insensitive
   value := token / quoted-string
   token := 1*<any (ASCII) CHAR except SPACE, CTLs, or tspecials>
