Uh, indeed, you're not trying to do what JAXB does, and I am doubtful
whether it will be of use to you at all. An XML document is, an XSD
describes, and the Java Binding API binds, *data structures*. They have
no concept of methods as such.

You'll probably be better off writing your own annotation parser and
generating the schema on the fly (and pondering whether to use JAXB
annotations or your own). See
<http://docs.oracle.com/javase/6/docs/technotes/guides/apt/index.html>
and
<http://docs.oracle.com/javase/6/docs/jdk/api/apt/mirror/overview-summary.html>
for more information.
