Thanks for the explanation and the diagram. It cleared things up for me.

That's why I said "be able to". 95% of the time the desired behavior
for directives will be to process the block argument as RST, and not
do any other RST processing. In those cases, you can decouple. If you
want something else, you have to muck with the inside of the parser.
