No doubt they're important, but the goal of my document is to provide
an overview of how lojban works from the perspective of its grammar. I
think the -clause details and magic words would distract too much from
that purpose. I don't plan on filling out mesko either. (But someone
can contribute descriptions if they like.)

I don't think it can be done in pure PEG, alas. Perhaps a source file
that generates a peg could be created. :) The source file could also
output a Rats! version that would be more compact and efficient than
the current version, which is quite huge dll-wise.

Thanks. Most helpful as an adjunct to Lojgloss, which shows the
production names as part of its interface. (Work on Lojgloss is
progressing, by the way. I hope to have a new web version, with
parsing support, available within a few weeks.)
