[wsrp-wsia] [change request #80] Passing a null sessionID toreleaseSessions

[Rich Thompson <richt2@us.ibm.com>]

Section: 6.5 releaseSession
Page/Line: 43/
Requested by: Andre Kramer
Old text: 
Proposed text: SessionIDs may be set to null in releaseSession() calls. In 
which case, the Consumer is signalling that any underlying HTTP session is 
no longer to be considered active. The Consumer may want to release any 
session identifiers it caused to be established in the scope of the HTTP 
session, independently of the HTTP session (but is likely to be supplying 
portletInstanceKeys).
