WS-ServiceGroup add method semantics question

["David W. Levine" <dwl@watson.ibm.com>]

A collegue has noticed the
following...

Version 1.0 of the WS-ServiceGroup specification describes the 
InitialTerminationTime parameter of the Add method of the 
ServiceGroupRegistration interface as: "An optional element,
indicating 
the requestor's suggestion for the initial setting of the termination
time 
resource property [WS-ResourceLifetime] of the ServiceGroupEntry 
WS-Resource."

The word "suggestion" suggests that the implementation could
perhaps 
ignore it, and create an Entry that has a different (longer, shorter)
termination time.  Since the only return from Add is the EPR of the
new 
Entry, it seems that the caller will have to immediately query the
Entry's 
properties to find out what actual termination time was used (since it
might be, say, Real Soon).

Is that the intended semantics of the InitialTerminationTime, or is there
some stronger behavioral requirement on the implementation?  It
would be 
preferable, I think, if the actual termination time were no earlier than
the InitialTerminationTime in the Add request, and/or if the reply from
Add included the actual termination time, so as not to have to do another
call to request it.
