The "right" answer is to use margin-left, which indents
relative to the containing block.  start-indent is
measured relative to the reference container, which is
usually the page.  The thread about using the body-start()
function outside of a fo:list-block seemed to conclude that
it wasn't appropriate.

But FOP doesn't seem to properly handle nested margin-left
indents.  XEP does.  So the "right" answer depends on your
FO processor.
