...and also, if I'm not mistaken, because changes are still being
made, so the tagset itself is something of a moving target. The
editors will perhaps have more to say on this, but it seems to me
that people starting to work with P5 should be very much aware that
it is still in development. Sort of like living in an unfinished
house--it's fine to walk through the walls for now, but don't be
surprised and hit your head when the sheetrock goes up...
