 Usage of the `break` element's attributes are described in the following table.
 
 | Attribute | Description | Required or optional |
 | ---------- | ---------- | ---------- |
-| `strength` | The relative duration of a pause by using one of the following values:<br/><ul><li>none</li><li>x-weak</li><li>weak</li><li>medium (default)</li><li>strong</li><li>x-strong</li></ul><br/><br/>Set `strength` to `none` to prevent automatic insertion of a prosodic break. | Optional |

 | `time`     | The absolute duration of a pause in seconds (such as `2s`) or milliseconds (such as `500ms`). Valid values range from 0 to 5000 milliseconds. If you set a value greater than the supported maximum, the service will use `5000ms`. If the `time` attribute is set, the `strength` attribute is ignored.| Optional |
 
 Here are more details about the `strength` attribute.
