I am not sure what you are talking about Martin, but "Xerces" is a fully active Apache Top Level Project: http://xerces.apache.org/
I am vaguely insulted by your continued use of the phrase "indians who worked on the code" and I am 1) not from India and 2) never worked on Xerces. You may be trying to reference "Crimson", which was the default XML parser in the JRE until it was replaced by Xerces around Java 5 or 6. Crimson did the job mostly OK, but had some serious problems and most folks didn't use it and used Xerces instead - hence the JDK replacement. I don't know the full history on Crimson, but Wikipedia claims it was also part of the Apache XML project. See http://en.wikipedia.org/wiki/Apache_XML "No longer developed projects Crimson: A Java XML parser derived from the Sun Project X Parser" In any case, it doesn't seem like you have all the facts straight here and as far as I know, Xerces supports XML Schema to the extent documented just fine (i.e. XSD validation).
