You've asked for Java classes, but you haven't said what you want the 
Java classes to do? Should they correspond to an interface with an 
infinite number of methods for everything you might ever want to do with 
an XML document?
XSL works because it has a single task: rendering (not necessarily on 
paper!). The interfaces between the snippets of XSL code are 
well-defined, because all they are doing is passing around rendered 
document sections. If you want the same for Java classes, then you must 
define what you want those Java classes to do, and define appropriate 
interfaces for them.
