There were no indications in the first posting that the target was HTML.
The code fragment posted used the standardized semantics (flow objects),
which led me to believe that was what you wanted.  The sample I proved
assumed the output was a back end that processed the standardized flow
objects, such as the RTF back end.

The function of nsgmls is to parse an SGML file and report on what is being
parsed, not to synthesize any particular markup.

A flow object tree is very useful for debugging, but I am not aware of any
programs (yet) to read one of JADE's flow object trees and processing it
into meaningful output.

Given that you wanted HTML, I recommend you use JADE's SGML back end.
Modifying my first example DSSSL script into one that uses the customized
flow objects and semantics of the SGML back end was quite straightforward.  

I've modified the example to illustrate both flow objects being explicitly
nested and flow objects being implicitly nested through the execution of
element construction rules.
