Hi Folks,

What XPath expression will tell me if the xs:duration value in this element is not negative:

<duration>_______</duration>

XSL F&O says:
..... Note that no ordering relation is defined on xs:duration values...

so you'll need to cast to a type that does have an ordering relation
either xs:yearMonthDuration or xs:dayTimeDuration so something like

xs:yearMonthDuration(duration) ge xs:yearMonthDuration(P0Y)
