Hi Stephane,
Thanks for your reply. To demonstrate why it would be good to have @le,
perhaps it will help to show the hack I currently have to use in order
to get all dates up to and including a "to" date:
let $to := "1800-01-01"
(: Hack: Add one day as ML doesn't understand le. :)
let $next := $to cast as xs:date + xs:dayTimeDuration("P1D")
return <constraint name="Dates-To">
<range type="xs:date" facet="false">
<bucket lt="{$next}" name="{$to}">Dates to {$to}</bucket>
<element ns="http://example.com/"; name="date"/>
<attribute ns="" name="to"/>
</range>
</constraint>
Best,
Tim Finney
