Valid values continued:
RM_PREVIEW_UNREGISTER
This is a request to verify the password
for an Unregister Request. The Request
ID is also verified. The request does not
get unregistered when this lifetime option
is used. This should be used only when
RmOperationType is RM_UNREGISTER.
RM_QUERY_REQUEST
The monitor request should be
automatically deleted by EMS as soon as
the resource value has been obtained from
the monitor. The client application does
not need to send an Unregister Monitor
Request. This is not supported for
resources where RmStateType is
RM_ASYNCHRONOUS.
The default is
RM_NON_PERSISTENT_REQUEST.
