compare dayTimeDuration ?

[Aaron Redalen]

Apologies if I've misunderstood your point, but the op functions are available to users via operators, are they not? 

For instance: 

op:date-greater-than($arg1 as xs:date, $arg2 as xs:date) as xs:boolean

Provides the implementation for an expression like:

(xs:date("2007-02-24") gt xs:date("1959-02-03"))

However, it probably could be made clearer to new users that op: functions are not designed to be called as functions, but using their corresponding operators.

Again, my apologies if I've misunderstood you in any way.

Sebastian, I suspect you just need to cast your values to xs:date.

I don't think this actually helps - the op:... functions are not  
available to users, and there is nothing else mentioned. Also, at  
least for me, I found that you need to read the regular XQuery spec,  
the F&O and the XML schema spec at the same time to find out the  
particular semantics of some operations. This is not something I  
would recommend or expect users to understand.

Martin
