This package uses the Date::Manip package to add an XQL node type
(called XML::XQL::Date) that can be used to represent dates and times.
The Date::Manip package can parse almost any date or time format imaginable.
(I tested it with Date::Manip 5.33 and I know for sure that it doesnt work
with 5.20 or lower.)
It also adds the XQL <B>dateB> function which creates an XML::XQL::Date
object from a string. See XML::XQL::Tutorial for a description of the date()
You can plug in your own Date type, if you dont want to use Date::Manip
for some reason. See XML::XQL and the XML::XQL::Date source file for
