    ****************************************************************
    A "feature not found" exception may be received while
    processing an "xmlns" or "xsitype" attribute of an XML element
    using the SAX parser.
    The exception occurs when using the Eclipse EMF libraries to
    process XML data, with the SAX parser selected as the XML
    parser, and with the SAX parser configured with namespace
    processing disabled and namespace-prefixes enabled.  That is,
    with a feature configuration where
    http://xml.org/sax/features/namespaces is 'false' and
    http://xml.org/sax/features/namespace-prefixes is 'true'.
    Having namespace processing disabled and namespace-prefixes
    enabled is not the default configuration which is used by the
    application server.  Therefore the exception should not occur
    from application server code but is mostly likely from stacked
    product or application code.
    

Problem conclusion

  • The Eclipse EMF XML parsing code was incorrectly determining
    if namespace processing was enabled and handling attributes as
    if it was enabled when it was not.
    
    The component which detects if namespace processing is enabled
    has been updated to use the features described above to
    determine the state of namespace processing.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.35, 8.0.0.10, and 8.5.5.4.  Please refer to
