Yes. I have multiple s/w endpoints. Each of which can be independently
on or off, so it maps onto BSC perfectly.

Oh, it has both. I just needed an On/Off state change message. BSC
supports that. I'm definitely not applying Text or Level to anything,
although I could massage Level into a "new emails/total emails"
type
thing if I applied enough force on the crowbar!

If I don't use BSC I end up with a schema that looks very similar but
lives in a different class. No point, I thought.

That's what I chose to do.

Sure do.

Well it's hard-coded with yet another "// ToDo:" comment to
expose the
setting through xFx.

In theory setting it to 0 (were it not a hard-coded constant in the
code) would achieve the same effect.

I've set it for a single burst.
