[1] I created a list of differences and talked to Dan about his suggestion for the defaults. The numbers in parentheses are Dan's suggestions, but he also asked me to post here to get a wider set of opinions on these values. This list is based on the code used in infinispan-core, so I still need to go through the server code to check the default values there.

Impractical without a ton of annotations, since the builder structure is 
very different from the XSD structure.

Server has a subsystem writer which recreates the configuration from the 
in-memory model, maybe it's worth adapting that.
