I think there are at least two relevant sections. Under the description of
<Terminate/> rules, it says that indeed the SP/IdP can choose to terminate
an active session if it wishes, implying that formal SLO is not going to

But you also have the end of that section that notes lag time is an issue,
and it's arguably worth remebering values for some period of time just to
smooth over any messages that come in after the fact.

I guess if I were implementing, I'd probably have more of a "mark dead" flag
in the record, not accept new sessions with it, but handle logout/etc. as
well as possible until I purge the record.
