如何在JSON模式中将特定属性值指定为依赖项？

Question

我知道我可以执行以下操作（来自http://spacetelescope.github.io/understanding-json-schema/reference/object.html#schema-dependencies）

{
  "type": "object",

  "properties": {
    "name": { "type": "string" },
    "credit_card": { "type": "integer" }
  },

  "dependencies": {
    "credit_card": {
      "properties": {
        "billing_address": { "type": "string" }
      },
      "required": ["billing_address"]
    }
  }
}

但是在我的情况下，当信用卡具有特定价值时，我只希望信用卡依赖于所需的帐单地址。这是我的尝试不起作用：

{
  "type": "object",

  "properties": {
    "name": { "type": "string" },
    "credit_card": { "type": "integer" },
    "billing_address": { "type": "string" }
  },

  "dependencies": {
    "credit_card": {
      "enum": [100000000000],
      "properties": {
        "billing_address": {}
      },
      "required": ["billing_address"]
    }
  }
}

我正在反对v4草案。
