In 4.x.  (There are users still using that version.)

I agree, I'd rather use the format attribute for what it appears
to have been designed for.  So we can do that in 5.x but not in 4.x.

Sure I'd be willing to do that, but probably not until the late
September
time frame.  I gather you're only interested in a 5.x solution which
means I'll probably still have to invent my own 4.x solution (which is
pretty much what I've outlined already).
