Data ref treated as number in everit-org/json-schema library to validate JSONSchema

Question

I am using https://github.com/everit-org/json-schema library to do serverside validation for JSONSchema it is failing when i use dataref in maximum validation

my schema property is like

"fromYear": {
            "array": false,
            "type": "number",
            "title": "From Year",
            "minimum": {
                "$data": "1/toYear"
             },
            "key": "fromYear",
            "required": false
        }

but when we call validate method of Schema then it throws error like

"#/properties/qualificationsection/items/properties/fromYear/minimum: expected type: Number, found: JsonObject"

JSON Schema supports minimum number as well as a jsonobject (ie., it supports union types) where we can specify data ref.

The library is unable to deal with this as is expecting minumum to always be of type number

$data is not a JSON Schema keyword at current (draft-7).

Some libraries attempt to implement it, as it is a suggestion for future drafts, but it is not currently part of the official specification.

There's no alternative to this. It simply isn't currently possible.
