I think a summary in some easily found spot is highly desirable. Presumbly
XML docs might be *large*. It will be a bind to have to wait for all
10MB to arrive before partial rendering with links visible. Also, a
threaded implementation might make use of a linkage summary to do behind
the scenes link work whilst simultaneously doing the rendering.
