Yes. IF the source block is named, the results block will be
replaced regardless of where it lives in the file, so adding
attributes above the results block works.

BUT, if the source block is not named then a duplicate results will be
created above the current results block w/ the attribute header when
the source block is re-evaluated.

I guess it's acceptable to require all source blocks to be named if
you want to have header attributes associated with the generated
results, but this is a significant incompatible change from the
behavior of the current exporter...
