A standard library of mathematical functions suitable for use in XPath, and
therefore in XQuery, has been defined at http://www.exslt.org/
<http://www.exslt.org/> . These are gradually being adopted by XSLT vendors,
and if there is user demand, I see no reason why XQuery vendors should not
implement the same functions.

Subject: Mathematical functions

is it possible to use mathematical functions in XQuery using a standardised
library with a dedicated namespace ?
If not, what is the best way to use functions not defined in the built-in
functions core library without defining them
into the XQuery itself ? Defining sin or tan using Taylor series may be very
Best regards.
