Yes, that would be good. I'm actually just thinking that it may be better
to move it to man_made= rather than barrier=, as you may get the situation
of barrier=berm + berm=barrier?
Bit premature I know!, but names for actual "types"? Guessing along the

=pollution-control, all of which are fairly self-explanatory.
Walls around explosive dumps, shooting ranges & so on - =protective?

True. A levee is (usually) a berm, while a dam could be, but a berm doesn't
*have* to be either a levee or a dam!

Hadn't thought about that, as that section was copied directly from the

Not quite. A berm is basically just a pile of dirt. The dirt can be bare or
covered with grass, it can be moulded into different shapes, heights or
widths / thicknesses, left loose or compacted, depending on the purpose
it's required for.

Thanks! That ties in with what I was thinking ^ of it being better coming
under man_made=, rather than barrier=
man_made=embankment (sloped wall) + embankment=berm (pile of dirt) +
berm="use" - fortification / protective / noise_control etc
That'll do for this post as it's turning into a novel!
