Thank you for your contribution Michael and Paul. I share your opinion about the http://www.exslt.org/ mathematical module. It may be integrated in the XQuery language since the modules will be fully specified by the Working Group. I will use it in our implementation ( http://www.gael.fr/drb and http://www.gael.fr/derby ) until next releases of the Working Draft.

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. Regards, Michael Kay -----Original Message----- From: Stéphane Mbaye [mailto:stephane.mbaye@gael.fr] Sent: 24 September 2002 08:11 To: XQuery Subject: Mathematical functions Hello, 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 inefficient. Best regards. Stephane.
