XTCE13 — Is rangeForm specialization needed for Change and Multi band alarms?

RangeForm now appears in Static, Change and the multi band. It's not clear these all make sense to me.

In the static ranges – having the red be the most severe inner band and green "good" on the outside does make sense although I get the impression the use cases are less in number than the standard way folks think of limits. (you're going too fast! not – you're not going fast enough!)

In the change alarm, which I think of mainly as deltas – again intuitively checking for big changes make sense. Unwanted big jumps are intuitive. But unwanted little jumps? That is big jumps are good? Is there a real use case – perhaps we can jam it into the annotation.

Finally for the multirange alarm. The rangeForm is at each band. I suspect but don't know that this was to change the range set meaning...
Intuitively "inside" would be something like this: [min, max] – where x is between them is "ok" ...

And "outside" would be (-inf, min] and [max, inf) ... that is ranges point 'away'...

But maybe not – who knows!? Given that though the default is "outside" when perhaps most would want it to be "inside" etc...

I just wonder if we have done this correctly or its slipped through and is overly general because we inherited the various types, etc...
