I think there are some books on XQuery coming up. Also, maybe your
product has some documentation with it?

What's the problem? Given four dates $a1, $a2, $b1, $b2 you jus need
to check if the points lie inside of the other range, no? And if you
have $a1 etc. really be xs:date elements you can simply use > and <.
You can use fn:trace by wrapping values in it, e.g. instead of
let $x := ...
return ...
you'd write:
let $x := trace(..., 'trace at foo point')
return ...
This is fully composable, so you can also wrap function calls in it etc.
Regards,
Martin
