JSON schema snippet generated for each resource type:

      "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"
      },

---

only specific configurations supported for a few resource types

cfn-lint already contains UpdatePolicy validation, so not going to replicate that here
