我试图用 ApiBlueprint MSON 表示法描述一个具有可变部分的对象。这是 ApiBlueprint 中的简单代码：
FORMAT: 1A
# Test API
## Services [/Service/{id}]
### GET Service info [GET]
+ Request (application/json)
+ Headers
Authorization: JWT <token>
+ Response 200 (application/json)
+ Attributes (array[ServiceResource], fixed)
# Data Structures
## Resource (object)
### Properties
+ id: `a6vhAo3FG` (string, fixed)
+ created_at: `2016-07-01T15:11:09.553Z` (string, required)
+ updated_at: `2017-11-22T08:07:55.002Z` (string, required)
## Service (object)
### Properties
+ type: tcp_service (string, required)
- One Of
- config (TcpService, required)
- config (IcmpService, required)
## ServiceResource (Resource)
### Properties
- Include Service
## TcpService (object)
### Properties
+ port: `80` (number, required)
+ request_str: `HEAD` (string, required)
+ expect_response_str: `200 OK` (string, required)
## IcmpService (object)
### Properties
+ timeout_ms: `1000` (number, required)
+ packet_size_bytes: `1000` (number, required)
+ ttl: `128` (number, required)
它在 apiary.io 中完美呈现，但在https://json-schema-validator.herokuapp.com中生成的 Json Schema 的验证会报告错误：
[ {
"level" : "error",
"schema" : {
"loadingURI" : "#",
"pointer" : "/items"
},
"instance" : {
"pointer" : "/0"
},
"domain" : "validation",
"keyword" : "additionalProperties",
"message" : "object instance has properties which are not allowed by the schema: [\"config\"]",
"unwanted" : [ "config" ]
} ]
也许我做错了什么？
有什么方法可以在 MSON 中描述对象具有提供正确 JSON 模式的变体部分的对象数组？
