//    with a message eliciting slot data (for example, PizzaSize): "What size
//    pizza would you like?".

// conclusion statements do not require a response. Some messages require only

// context about the message in the response that you can use to enhance client
// behavior, such as displaying the appropriate client user interface. Consider
// the following examples:
//
//    * If the message is to elicit slot data, Amazon Lex returns the following
//    context information: x-amz-lex-dialog-state header set to ElicitSlot x-amz-lex-intent-name
//    header set to the intent name in the current context x-amz-lex-slot-to-elicit
//    header set to the slot name for which the message is eliciting information
//    x-amz-lex-slots header set to a map of slots configured for the intent
//    with their current values
//
//    * If the message is a confirmation prompt, the x-amz-lex-dialog-state
//    header is set to Confirmation and the x-amz-lex-slot-to-elicit header
//    is omitted.
//
//    * If the message is a clarification prompt configured for the intent,
//    indicating that the user intent is not understood, the x-amz-dialog-state
//    header is set to ElicitIntent and the x-amz-slot-to-elicit header is omitted.
//
