The best reference is the spec. I think some of the JavaOne
presentations downloadable from the downloads section also includes a
few slides about how this works in general. It would be nice to have
more comprehensive yet accessible documentation (like a book, maybe?),
but there's none yet.
JAXB runtime looks at properties (getter/setter) and fields (normally
public ones, but also the ones with explicit JAXB annotations.)
Beyond that, I think you should probably look at examples in the RI
distribution, and do some experiments.
