Property schema based on the values of other properties?

[clusterf]

Is there the possibility of defining the min/max of a property based on the value of other properties?

Ex:

{
    "lowerValue": {
        "type": "integer",
        "minimum": 0,
        "maximum": 100
    },
    "upperValue": {
        "type": "integer",
        "minimum": 0,
        "maximum": 100
    },
    "targetValue": {
        "type": "integer",
        "minimum": "#lowerValue ?!?",
        "maximum": "#upperValue ?!?"
    }
}

The $ref keyword is essentially what you use for this sort of thing.
