oh god. I must have missed some combination when I had this idea. so what happens is that the data behind the dev OSM API seems partial. so when I started with overpass to do a complex query, the then OSM base API did not find the elements by id! the Prod API does though. I don't think the XAPI layer can do a search by ID (at least I haven't found one).
but not I can finally tie things together. Thanks for putting me back on track!
