SAXON: Conditions of Use


The contents of the downloaded file (, with the exception of the Ælfred parser (see below), are subject to the Mozilla Public License Version 1.0 (the "License"); you may not use this file except in compliance with the License. You may obtain a copy of the License at

Software distributed under the License is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY KIND, either express or implied. See the License for the specific language governing rights and limitations under the License.

The Original Code of SAXON comprises all those components which are not explicitly attributed to other parties. It does not include the Ælfred parser, which is redistributed under the licence described below.

The Initial Developer of the Original Code was Michael Kay. Individual modules identified as being created by James Clark, David Megginson, or John Cowan include separate IPR notices. All Rights Reserved.

Until January 2001 Michael Kay worked for International Computers Limited (ICL, now part of Fujitsu), and from February 2001 to January 2004 he worked for Software AG. These two companies both sponsored the development of Saxon and authorised its release under this license, but are not themselves parties to the license. Michael Kay now runs his own company, Saxonica, which has taken over all responsibility for Saxon development and support.

For reasons of continuity, the domain name is retained in package names and namespace URIs with the tacit consent of ICL, but this should not be taken to imply any ongoing ICL involvement.

If you produce a product that includes or requires SAXON, please refer to it as "The SAXON XSLT Processor from Michael Kay", and include the URL of the home page, which is at

There is no guarantee of technical support, though I am usually able to answer enquiries within a few days. Please subscribe to the mailing list available at and raise any enquiries there. Also check the Saxon project pages on sourceforge for details of known errors; all bugs are listed there as soon as I have sufficient evidence to describe the nature of the problem.


Included in the Saxon distribution is a modified version of the Ælfred XML parser originally developed by David Megginson at Microstar (no longer in existence). I have taken the relevant part of David Brownell's Ælfred2 distribution, repackaged it, and fixed a few bugs. All changes are clearly documented in the source code.
