Using oneOf basing on value attribute

[NicolaSpreafico]

Hi,
I have a json configured as this example:

{
  "id": 1,
  "values": [
    {
      "type": "A",
      "values": {
        "foo": "bar"
      }
    },
    {
      "type": "B",
      "values": {
        "foo": [
          "bar",
          "baz"
        ]
      }
    },
    {
      "type": "C",
      "values": {
        "foo": {
          "bar": "baz"
        }
      }
    }
  ]
}

Basing on the value of key type (which is enum), the schema for property values is different.
Is there a way to create a conditional-like (like with anyOf) but selecting the proper schema basing on the value of type property?

@NicolaSpreafico I think you are looking for something like this (which assumes you are using draft-07, a.k.a. draft-handrews-json-schema-validation-01):

{
  "type": "object",
  "properties": {
    "id": {"type": "integer"},
    "values": {
      "type": "array",
      "items": {
        "required": ["type"],
        "oneOf": [
          {   
            "if": {"properties": {"type": {"const": "A"}}},
            "then": {"properties": {"foo": {"type": "string"}}}
          },  
          {   
            "if": {"properties": {"type": {"const": "B"}}},
            "then": {"properties": {"foo": {"type": "array"}}}
          },  
          {   
            "if": {"properties": {"type": {"const": "C"}}},
            "then": {"properties": {"foo": {"type": "object"}}}
          }   
        ]   
      }   
    }   
  }
}

No further question or response for a couple months, so I'm assuming this was a good enough answer and closing.
