Each block returned from the Textract API have a specific type that convey what each block is or represents.

For text detection operations (done by the DetectDocumentText processors), a block can take one of the following types:

| Identifier | Description                                                                                                                   |
| ---------- | ----------------------------------------------------------------------------------------------------------------------------- |

| `WORD`     | A word detected on a document page. A word is one or more ISO basic Latin script characters that are not separated by spaces. |
