I am looking for an XSLT 1.0 template that computes the number of days
between two dates.  I don't want to reinvent the wheel, but I was unable to
find such a template browsing around in Google.  Can anyone post or point me
to one?

I know there is an EXSLT date:difference template that computes the duration
between two dates, but it can include years and months.  It is not a trivial
task converting these components of a duration to the number of days, as I
would have to take into account leap years and the different number of days
in each month.
