 ### Azure Core Library Exceptions
 
 #### AzureError
+
 AzureError is the base exception for all errors.
+
 ```python
 class AzureError(Exception):
     def __init__(self, message, *args, **kwargs):
-        self.inner_exception = kwargs.get('error')
+        self.inner_exception = kwargs.get("error")
         self.exc_type, self.exc_value, self.exc_traceback = sys.exc_info()

         self.exc_msg = "{}, {}: {}".format(message, self.exc_type, self.exc_value)  # type: ignore

+        self.continuation_token = kwargs.get("continuation_token")
         super(AzureError, self).__init__(self.message, *args)
 ```
 
 *message* is any message (str) to be associated with the exception.
 
 *args* are any additional args to be included with exception.
 
-*kwargs* are keyword arguments to include with the exception. Use the keyword *error* to pass in an internal exception.
+*kwargs* are keyword arguments to include with the exception. Use the keyword *error* to pass in an internal exception and *continuation_token* for a token reference to continue an incomplete operation.
 
 **The following exceptions inherit from AzureError:**
 
 #### ServiceRequestError
+
 An error occurred while attempt to make a request to the service. No request was sent.
 
 #### ServiceResponseError
+
 The request was sent, but the client failed to understand the response.
 The connection may have timed out. These errors can be retried for idempotent or safe operations.
 
 #### HttpResponseError
+
 A request was made, and a non-success status code was received from the service.

 class HttpResponseError(AzureError):
