In 
<http://tools.ietf.org/html/draft-nottingham-linked-cache-inv-02#section-5>, 
it would be good to define the edge parsing edge cases, such as:

- multiple instances of the directive,

- missing argument,

- use of quoted-string.

I would propose to say that:

- the parameter value needs to follow the delta-seconds ABNF after 
applying generic C-D parsing,

- that a missing argument is to be treated as empty string (thus 
invalid), and

- that specifying multiple instances makes the Cache-Control header 
invalid with respect to this directive (thus the header field should be 
processed as if inv-maxage wasn't specified at all).

Optimally, including examples :-)

Best regards, Julian
