 Request and response formats
 ============================
 
-The OpenStack Compute API supports JSON request and response formats.
-
-Request format
-~~~~~~~~~~~~~~
-
-Use the ``Content-Type`` request header to specify the request format.
-This header is required for operations that have a request body.
-
-The syntax for the ``Content-Type`` header is:
-
-.. code::
-
-    Content-Type: application/FORMAT
-
-Where ``FORMAT`` is ``json``.
-
-Response format
-~~~~~~~~~~~~~~~
-
-Use one of the following methods to specify the response format:
-
-``Accept`` header
-The syntax for the ``Accept`` header is:
-
-    .. code::
-
-        Accept: application/FORMAT
-
-Where *``FORMAT``* is ``json`` and the default format is ``json``.
-
-Query extension
-Add a ``.json`` extension to the request URI. For example, the ``.json`` extension in the following list servers URI request specifies that the response body is to be returned in JSON format:
-
-    **GET** *``publicURL``*/servers.json
-
-If you do not specify a response format, JSON is the default.
+The OpenStack Compute API only supports JSON request and response
+formats, with a mime-type of ``application/json``. As there is only
+one supported content type, all content is assumed to be
+``application/json`` in both request and response formats.
 
 Request and response examples
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-You can serialize a response in a different format from the request
-format.
-
 The examples below show a request body in JSON format.
 
-.. note:: Though you may find outdated documents with XML examples, XML support
-   in requests and responses has been deprecated for the Compute API v2
-   (stable) and v2.1 (experimental).
-
 **Example: JSON request with headers**
 
 | POST /v2/010101/servers HTTP/1.1
 |  Host: servers.api.openstack.org
-|  Content-Type: application/json
-|  Accept: application/xml
