request's attribute assertion lifetime?

[Frank Siebenlist <franks@mcs.anl.gov>]

I just came accross the fact that the request's attribute element has an 
optional InstantIssue element to indicate the date and time at which the 
attribute was issued, but you can't seem to specify a duration validity interval.

Any reason for that?

Regards, Frank.
