Duplicate Operation Paging Parameters in S3

[IliyanDraganov]

I think this is the same issue you had with EC2.
For example the following operation:

    "operationId": "ListMultipartUploads",
    "description": "This operation lists in-progress multipart uploads.",
    "externalDocs": {
      "url": "http://docs.amazonwebservices.com/AmazonS3/latest/API/mpUploadListMPUpload.html"
    },
    "responses": {
      "200": {
        "description": "Success",
        "schema": {
          "$ref": "#/definitions/ListMultipartUploadsOutput"
        }
      }
    },
    "parameters": [
      {
        "name": "Bucket",
        "in": "path",
        "required": true,
        "description": "<p/>",
        "type": "string"
      },
      {
        "name": "delimiter",
        "in": "query",
        "required": false,
        "description": "Character you use to group keys.",
        "type": "string"
      },
      {
        "name": "encoding-type",
        "in": "query",
        "required": false,
        "description": "Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. An object key may contain any Unicode character; however, XML 1.0 parser cannot parse some characters, such as characters with an ASCII value from 0 to 10.

        "type": "string",
        "enum": [
          "url"
        ]
      },
      {
        "name": "key-marker",
        "in": "query",
        "required": false,
        "description": "Together with upload-id-marker, this parameter specifies the multipart upload after which listing should begin.",
        "type": "string"
      },
      {
        "name": "max-uploads",
        "in": "query",
        "required": false,
        "description": "Sets the maximum number of multipart uploads, from 1 to 1,000, to return in the response body. 1,000 is the maximum number of uploads that can be returned in a response.",
        "type": "integer"
      },
      {
        "name": "prefix",
        "in": "query",
        "required": false,
        "description": "Lists in-progress uploads only for those keys that begin with the specified prefix.",
        "type": "string"
      },
      {
        "name": "upload-id-marker",
        "in": "query",
        "required": false,
        "description": "Together with key-marker, specifies the multipart upload after which listing should begin. If key-marker is not specified, the upload-id-marker parameter is ignored.",
        "type": "string"
      },
      {
        "name": "MaxUploads",
        "type": "string",
        "in": "query",
        "description": "Pagination limit",
        "required": false
      },
      {
        "name": "KeyMarker",
        "type": "string",
        "in": "query",
        "description": "Pagination token",
        "required": false
      },
      {
        "name": "UploadIdMarker",
        "type": "string",
        "in": "query",
        "description": "Pagination token",
        "required": false
      },
      {
        "name": "uploads",
        "in": "query",
        "required": true,
        "type": "boolean",
        "allowEmptyValue": true,
        "enum": [
          true
        ]
      }
    ]
  }

requires max-uploads and MaxUploads, key-marker and KeyMarker, upload-id-marker and UploadIdMarker.
According to Amazon S3 API Reference you don't need both and you need them in PascalCase.
