Re: [xsl] testing dates

[David Carlisle <davidc@xxxxxxxxx>]

XSLT 1 only has numeric less than operation  so if you give it to
strings they are each converted to a number before comparing 2004-06-27
and 2004-09-05 both compare to NaN (Not-A-Number) I leave it to IEEE
lawyers to confirm what exactly the value of NaN < NaN should be
but I would guess that it's false, as you say.

In XSLT2 you could cast the strings to dates then do a date-aware
comparison.
