// StartDocumentTextDetection API operation for Amazon Textract.
//
// Starts the asynchronous detection of text in a document. Amazon Textract
// can detect lines of text and the words that make up a line of text.
//
// StartDocumentTextDetection can analyze text in documents that are in JPEG,
// PNG, and PDF format. The documents are stored in an Amazon S3 bucket. Use
// DocumentLocation to specify the bucket name and file name of the document.
//
// StartTextDetection returns a job identifier (JobId) that you use to get the
// results of the operation. When text detection is finished, Amazon Textract
// publishes a completion status to the Amazon Simple Notification Service (Amazon
// SNS) topic that you specify in NotificationChannel. To get the results of
// the text detection operation, first check that the status value published
// to the Amazon SNS topic is SUCCEEDED. If so, call GetDocumentTextDetection,
// and pass the job identifier (JobId) from the initial call to StartDocumentTextDetection.
//
// For more information, see Document Text Detection (https://docs.aws.amazon.com/textract/latest/dg/how-it-works-detecting.html).
//
// Returns awserr.Error for service API and SDK errors. Use runtime type assertions
// with awserr.Error's Code and Message methods to get detailed information about
// the error.
//
// See the AWS API reference guide for Amazon Textract's

//
// Returned Error Types:
//   * InvalidParameterException
//   An input parameter violated a constraint. For example, in synchronous operations,
//   an InvalidParameterException exception occurs when neither of the S3Object
//   or Bytes values are supplied in the Document request parameter. Validate
//   your parameter before calling the API operation again.
//
//   * InvalidS3ObjectException
//   Amazon Textract is unable to access the S3 object that's specified in the
//   request.
//
//   * UnsupportedDocumentException
//   The format of the input document isn't supported. Documents for synchronous
//   operations can be in PNG or JPEG format. Documents for asynchronous operations
//   can also be in PDF format.
//
//   * DocumentTooLargeException
//   The document can't be processed because it's too large. The maximum document
//   size for synchronous operations 5 MB. The maximum document size for asynchronous
//   operations is 500 MB for PDF files.
//
//   * BadDocumentException
//   Amazon Textract isn't able to read the document.
//
//   * AccessDeniedException
//   You aren't authorized to perform the action.
//
//   * ProvisionedThroughputExceededException
//   The number of requests exceeded your throughput limit. If you want to increase
//   this limit, contact Amazon Textract.
//
//   * InternalServerError
//   Amazon Textract experienced a service issue. Try your call again.
//
//   * IdempotentParameterMismatchException
//   A ClientRequestToken input parameter was reused with an operation, but at
//   least one of the other input parameters is different from the previous call
//   to the operation.
//
//   * ThrottlingException
//   Amazon Textract is temporarily unable to process the request. Try your call
//   again.
//
//   * LimitExceededException
//   An Amazon Textract service limit was exceeded. For example, if you start
//   too many asynchronous jobs concurrently, calls to start operations (StartDocumentTextDetection,
//   for example) raise a LimitExceededException exception (HTTP status code:
//   400) until the number of concurrently running jobs is below the Amazon Textract
