Robert has strongly suggested this section (3.6) of Conveyance
include an event package - with rules of usage. After talking with
him about it, I agree. This will be a new event package and will
only allow a single (Expires: 0) dereference (i.e., one NOTIFY
containing the PIDF-LO), and not allow pending subscriptions or
target tracking (i.e., numerous NOTIFYs returned).

The new event package will likely be called something like
"location-deref", verses something else like "location-tracking" for
a future effort that's out of scope for Conveyance.

Rohan, I'm open to your suggestions on how to further make section
3.6 clearer, as Conveyance right now doesn't allow "raw" location to
be sent anywhere.
