/**
 *
 *
 * <pre>
 * Represents a response message that can be returned by a conversational agent.
 * Response messages are also used for output audio synthesis. The approach is
 * as follows:
 * * If at least one OutputAudioText response is present, then all
 *   OutputAudioText responses are linearly concatenated, and the result is used
 *   for output audio synthesis.
 * * If the OutputAudioText responses are a mixture of text and SSML, then the
 *   concatenated result is treated as SSML; otherwise, the result is treated as
 *   either text or SSML as appropriate. The agent designer should ideally use
 *   either text or SSML consistently throughout the bot design.
 * * Otherwise, all Text responses are linearly concatenated, and the result is
 *   used for output audio synthesis.
 * This approach allows for more sophisticated user experience scenarios, where
 * the text displayed to the user may differ from what is heard.
 * </pre>

   * <pre>
   * Represents a response message that can be returned by a conversational agent.
   * Response messages are also used for output audio synthesis. The approach is
   * as follows:
   * * If at least one OutputAudioText response is present, then all
   *   OutputAudioText responses are linearly concatenated, and the result is used
   *   for output audio synthesis.
   * * If the OutputAudioText responses are a mixture of text and SSML, then the
   *   concatenated result is treated as SSML; otherwise, the result is treated as
   *   either text or SSML as appropriate. The agent designer should ideally use
   *   either text or SSML consistently throughout the bot design.
   * * Otherwise, all Text responses are linearly concatenated, and the result is
   *   used for output audio synthesis.
   * This approach allows for more sophisticated user experience scenarios, where
   * the text displayed to the user may differ from what is heard.
