Hi, After a look at the notices and peeking inside all of the jars I think I've worked out what we need to add.
The following are used in saxon.jar: UNICODE notice CERN notice Resolver notice THAI notice The following are not use or used in other jars: ANT notice - not used Xerces notice - used in saxon9-dom.jar JAMESCLARK notice - used in saxon9-xpath.jar And there are only in the .net version of the software: FRIJTERS notice GPL + Classpath notice From http://www.oxygenxml.com/archives/xsl-list/200602/msg00576.html: "and also to Jeroen Frijters who produced the IKVMC cross-compiler on which the technology depends. The Saxon code is still written in 100% Java, except for the new API front-end which is in C#. The Java code is compiled as normal, and the byte-code is then translated into native MSIL for the .NET platform using the IKVMC compiler" See also http://www.ikvm.net/userguide/ikvmc.html Any differing opinions? Thanks, Justin
