content_element could be an anyOf definition

[mauro-moreno]

content_elements is defined in trait_content_element.json as an array of content_element defined in utils/content_element.json. But, what specificiation doesn't explain is that could also be replaced by any schema defined in story_elements

Should not be the definition of content_element the reference to any of that schemas?

Current behavior:

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "id": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/utils/content_element.json",
  "title": "An element that can be listed as part of content elements",
  "description": "An item that conforms to this schema can be rendered in a sequence",
  "type": "object",
  "additionalProperties": {},
  "properties": {
    "type": {
      "type": "string"
    },
    "_id": {
      "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_id.json"
    },
    "subtype": {
      "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_subtype.json"
    },
    "channels": {
      "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_channel.json"
    },
    "alignment": {
      "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_alignment.json"
    },
    "additional_properties": {
      "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_additional_properties.json"
    },
    "gallery_properties": {
      "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_gallery_properties.json"
    }
  },
  "required": [ "type" ]
}

Expected behavior:

{
  "anyOf": [
    {
      "$schema": "http://json-schema.org/draft-04/schema#",
      "id": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/utils/content_element.json",
      "title": "An element that can be listed as part of content elements",
      "description": "An item that conforms to this schema can be rendered in a sequence",
      "type": "object",
      "additionalProperties": {},
      "properties": {
        "type": {
          "type": "string"
        },
        "_id": {
          "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_id.json"
        },
        "subtype": {
          "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_subtype.json"
        },
        "channels": {
          "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_channel.json"
        },
        "alignment": {
          "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_alignment.json"
        },
        "additional_properties": {
          "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_additional_properties.json"
        },
        "gallery_properties": {
          "$ref": "https://raw.githubusercontent.com/washingtonpost/ans-schema/master/src/main/resources/schema/ans/0.10.5/traits/trait_gallery_properties.json"
        }
      },
      "required": [ "type" ]
    },
    {
      "$ref": "https://github.com/washingtonpost/ans-schema/blob/master/src/main/resources/schema/ans/0.10.5/story_elements/blockquote.json"
    },
    {
      "$ref": "https://github.com/washingtonpost/ans-schema/blob/master/src/main/resources/schema/ans/0.10.5/story_elements/code.json"
    }
    ...
  ]
}

Use case:
I'm using a mapping tool from json schema to classes and I have to import all that schemas apart because they are not referenced.
