I have no intention to raise discussions of changing patterns to 
recognize beginning and end of objects or extending of syntax.

My guess is that pandoc may use bottom-up, not top-down approach. I 
admit, my opinion may be biased by reading complains concerning 
unexpected behavior of current implementation. Perhaps besides 
advantages pandoc parser has downsides. I would not be surprised if 
bottom up parser is unbearable without some tool that generates code for 
provided rules.

By the way, is it explicitly specified that within an element namely 
top-down strategy must be used to recognize objects?
