We think, that xml-apis.jar is a snapshot, build from the sources located here: https://svn.apache.org/repos/asf/xerces/xml-commons/trunk/java/external/. The version 1.4.02 can be found in https://svn.apache.org/repos/asf/xerces/xml-commons/trunk/java/external/build.xml

Since the version 1.4.02 was never released we decided to ignore the xml-apis.jar in the xalan distribution and to use the wellknown version 1.4.01.

Best regards, Jens

    Even setting the maven question aside for a moment, where does this
    xml-apis.jar even come from? As I noted, the manifest of the
    xml-apis.jar that comes with the xalan 2.7.3 download indicates a
    version of 1.4.02 (Implementation-Version). It also gives
    "Implementation-URL: http://xml.apache.org/commons/"; But following
    that
    link to the xml commons project, I can find no download for
    1.4.02, only
    1.4.01. Xalan does not provide the source that that jar in it's
    source
    download as far as I can tell.
