My understanding of NVDL is that its main purpose is validation and 
JNVDL thus implements standard Java API for invoking validation. So when 
your document is valid, there is no return. If there are some errors (be 
it validation problem on NVDL level, or validation errors against 
particular schema referenced from NVDL) you get these errors (as 
exceptions, or you can register your own ErrorHandler to handle them on 
your own).

Of course, JNVDL internally does sectioning of input XML document and 
then dispatches these sections (fragments) for validation against 
particular schemas (you can monitor this process by using -d option on 
command line interface). So it is possible to create some API which can 
be used to read fragments and their schemas (because JNVDL knows this), 
but it is not big priority (at least now) for us.
