    A preference token MAY specify a value.  Empty, or zero length values
    on both the preference token and within parameters are equivalent to
    no value being specified at all.  The following, then, are
    equivalent:

      Prefer: foo; bar=""
      Prefer: foo=; bar
      Prefer: foo=""; bar=

In the above examples, the second and the third one are invalid (missing 
value after "="). Bad examples, or bug in the ABNF? (I'd prefer the former).

Best regards, Julian
