A few lines down you say "generate an XSD which can be used by JAXB for 
marshalling and unmarshalling".

You can have javac use an annotation processor, if you want to do your 
work on compilation time.  In your case you would likely need to to some 
processing after compiling all classes in order to be able to combine 
information obtained from individual classes into a single XSD (if only 
for including all other XSD snippets).

 From what I understand about your goal you should probably generally 
distinguish two things here:

1. creating objects
2. invoking methods

JAXB might help you with 1 but certainly not with 2.  Also, you need a 
way to define variables to store references to created objects in so you 
can use them in method calls.  So, basically your XML needs to be able 
to store... what?  Basically you want an interpreter to execute Java 
code, don't you?  Thinking a few corners further you'll notice that 
there is actually already a way to specify sequences of method 
invocations: Java code.  You might be better off with some BeanShell 
solution in the end.  You get editors with semantic insight for free 
(it's your IDE) etc.

Kind regards
