I agree a RELAX NG viewer would be very nice to have. Writing the viewer in 
Java would be one possibility.  Another possibility might be generating 
SVG.  SVG has quite powerful interactive features, which should (I think) 
make it possible to interactively expand/collapse portions of the diagram 
in a similar manner to XMLSpy.  The advantage is that users who want to 
view the diagram wouldn't require any special tools; they would only 
require a standard SVG viewer (which in fullness of time I expect to become 
ubiquitous).
