Again the revision marks are pretty extensive, so the versions without
revisions are recommended.
1 Change History
The following changes were made from the July 7, 1998 to create the May 19,
1999 version:
1. Added the lease time concept from Jini and SLP event
notification mechanisms, where the client requests a lease, but may be
granted more or less, depending on the "notify-lease-time-supported
(rangeOfInteger) attribute.
2. Added "notify-lease-time-default" so that the client
can request the "usual", if it doesn't care.
3. Added returning the subscription ID in the
Renew-Subscription response in case the implementation needs to change the
ID.
4. Added some issues.
