I looked over your discussion and I think that above is the point.
The standard interface already exists. So I would introduce a factory
class instantiating readers/writers using additional hints i.e.:

class XmiReaderFactory {  
  XmiReader create(ContentHandler, XMIReferenceResolver);
  XmiReader create(XMIReferenceResolver);
  // ...
}

class XmiWriterFactory {
  XmiWriter create(ContentHandler, XMIReferenceProvider);
  XmiWriter create(XMIRefernceProvider);
  // ...
}

Unfortunately methods taking ContentHandler may produce
JMI interface implementations with modified semantics 
(I not sure if it is allowed). If it is not allowed then
you can drop it (pipelining nor pretty printing is not 
hard requirement AFAIK).

Anyway next round will be probably necessary :-)
