Aside from how "smart" it is, I don't see any other way to do it,
except to decompose the node into flat text and process it manually.
That's what I did for my ASCII output stylesheet, except I could never
get it to do any processing on child nodes.

I _finally_ got around to fiddling with this over the weekend, and
sort of got it working.  At least in principle.  The problem is that
the content that I want to break across page boundaries is always
contained in a single <speech> element, which means that it always
ends up in a single table-cell.

Is it possible to decompose a paragraph flow object into line-field
flow objects, and then stick each line into a separate row/cell?  If I
could do that, all my problems would be solved.  Or is line wrapping
handled by the backend, and thus out of reach of DSSSL?

Or alternatively, can I force a single multi-line table-cell to break
at the page boundaries?  Currently, it forces the cell to the next
page if it doesn't all fit on the current page.

I tried setting the n-rows-spanned property of the table-cell, but
that didn't quite work.  For example, when I set it to 3, the tex
backend allocated space for 1/3 of the content (as I expected);
unfortunately, the other 2/3 of the content overlapped the text
immediately following the table.  Maybe I didn't set it all up
correctly...I did a lot of half-blind fiddling.  (c;
