[infinispan-dev] Differences between default values in the XSD and the code...Part One

At this point, no one has disagreed with the default values that Dan suggested, so I am going to use these in the coming pull request. I am still checking the server defaults vs the XSD.

The discussion about keeping the XSD and code synchronized should continue, and hopefully we'll come to a solution that is more automatic than the current state. Removing JAXB may have been the correct decision, but the replacement seems to have created a bigger maintenance problem.
