Assumptions:
The object associated with object or anchor index
is an nsIAccessible.
A URI can be represented by the nsIURI interface
(or nsIURL interface).
Note that an object which supports nsIAccessibleHyperlink
does *not* generally implement nsIAccessible, unlike the
case of the other nsiAccessible* interfaces in this directory.
Aaron: would the nsISupports return from
getObject be queryable for nsIURI and nsIURL directly?
