// 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,
// TIFF, 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)
