minExclusive and maxExclusive

(Low priority)

Looking at JSON Schema, one thing I noticed JCR doesn't support is exclusive ranges. E.g.:

    "price": {
        "type": "number",
        "exclusiveMinimum": 0
    },

While a low priority feature I think we should support it.

CDDL takes the Ruby route for this of using .. for inclusive range and ... for exclusive range. I think this is confusing, especially for something that is unlikely to be used that often.

The easiest thing would be to define some suitable annotations. For example:

"range" : @{exclude-min} @{exclude-max} 0.0..100.0

(I've tried to come up with some short, meaningful names, even though they are not 100% formal computing jargon. Other names could be used.)

Other options might be:

"range" : !0.0..!100.0

Or:

"range" : 0.0<..<100.0

I like the annotation option as these are likely to be seldom used. This seems easy enough to do. We should include it.

OK. I'll see if I can add that in to the Ruby.
