I flew the KFWN VOR or GPS-A (http://204.108.4.16/d-tpp/0506/05412VGA.PDF)
this morning with a CNX-80. Annoyingly, ANKLE (the stepdown fix) is not in
the database. You get SAX-MAGLV. It seems like SAX-ANKLE-MAGLV would
make a lot more sense. Is the some reason it's left out of the database?

It's an overlay, so someone at Jeppesen made a coding judgment to treat it as
an ATD stepdown fix. I believe that is the protocol agreed upon for GPS final
approach segment stepdowns, but having said that, I suspect they are treated
both ways.
