// Inspects the clinical text for a variety of medical entities and returns
// specific information about them such as entity category, location, and
// confidence score on that information. Amazon Comprehend Medical only detects
// medical entities in English language texts. The DetectEntitiesV2 operation
// replaces the DetectEntities operation. This new action uses a different model
// for determining the entities in your medical text and changes the way that some
// entities are returned in the output. You should use the DetectEntitiesV2
// operation in all new applications. The DetectEntitiesV2 operation returns the
// Acuity and Direction entities as attributes instead of types.
