Okay, so you are trying to build a groff back-end using Jade! Good luck. There
was some discussion on this list about a year ago about writing back-ends using
DSSSL itself. I think the conclusion was that back-ends tend to have a lot of
state dependent processing (e.g., remembering the fonts, indents, etc.) that do
no lend themselves well to DSSSL's side-effect free nature.

As you have described your application, what you are seeking is really an
optimization (only generating output for those anchors that are actually
referenced). Why not just generate output for all of them?

BTW, someone may already be working on a C++ groff back-end for Jade.
