Could ideally re-use schemas already passed in for linting itself:
aws-cloudformation/cfn-lint#1732

---

schema/all-spec.json just needs another definition per schema:

  "RESOURCE_TYPE" : {
    "type" : "object",
    "description" : "URL",
    "properties" : {
      # attributes: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-product-attribute-reference.html
      "Type" : {
        "description" : "URL",
        "type" : "string",
        "enum" : [ "RESOURCE_TYPE" ]
      },
      "Properties" : RESOURCE_SCHEMA
    },
    "required" : [ "Type", "Properties" ], # Properties required only if some properties are required
    "additionalProperties" : false
  },

attributes snippet:

      "DependsOn" : {
        "type" : [ "string", "array" ],
        "items" : {
          "type" : "string"
        }
      },
      "Metadata" : {
        "description" : "https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-metadata.html",
        "type" : "object"
      },
      "DeletionPolicy" : {
        "description" : "https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html",
        "type" : "string",
        "enum" : [ "Delete", "Retain", "Snapshot" ]
      },
      "UpdateReplacePolicy" : {
        "description" : "https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-updatereplacepolicy.html",
        "type" : "string",
        "enum" : [ "Delete", "Retain", "Snapshot" ]
      },
      "CreationPolicy" : {
        "description" : "https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-creationpolicy.html",
        "type" : "object"
      },
      "UpdatePolicy" : {
        "description" : "https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-updatepolicy.html",
        "type" : "object"
      },

and resources patternProperties needs to reference that definition:

         , {
          "$ref" : "#/definitions/RESOURCE_TYPE"
        }

although VSCode may need to be restarted between schema patches? Only way I've been able to get it to pick up edits so far.. but maybe just the extension's client server could be restarted or something? @kddejong would know more than me on that side of things :)

debating JSON patch for the implementation:

[
   {
      "op":"add",
      "path":"/definitions/RESOURCE_TYPE",
      "value":{}
   },
   {
      "op":"add",
      "path":"/definitions/resources/patternProperties/^[a-zA-Z0-9]{1,255}$/oneOf/-",
      "value":{
        "$ref" : "#/definitions/RESOURCE_TYPE"
      }

We have this in now. There may be ways to improve it but those are future issues.
