Add() and Subtract() have been part of FXSL
(http://fxsl.sourceforge.net/) since 2001.

There are a lot of other useful functions in FXSL (corresponding to
almost all functions in Haskell's Prelude module)  that aren't defined
in the XPath/XQuery FO standard.

I must find some time to produce FXSL 3 -- now when its use would be
most easy in conjunction with XPath 3.

Cheers,

The examples at

would seem to suggest that primitives such as + and - cannot be passed as
values.

Correct?
