At first, I could not see the same output. It seems to be again a discrepancy 
between asciidoc.py and asciidoctor. Only asciidoctor is producing this 
output, and for me, it looks like a bug in asciidoctor.

Indeed, open blocks cannot be nested [1]. But, the first open block is not 
necessary as it is a workaround for the missing knowledge of multi-level 
definition lists.

Something along the following lines seems to work with asciidoctor while 
preserving the original paragraph nesting:
