Hmm, this doesn't seem like valid reStructed Text. What do you want to do here? A list? Then it should look like:

````rst
will allow alternate input formats like:

* ``216f-ff40-98d9-11e3-a5e2-0800-200c-9a66``
* ``{216fff40-98d9-11e3-a5e2-0800200c9a66}``
* ``216fff4098d911e3a5e20800200c9a66``
````

Or did you want to create a code block? Then you need to use:

````rst
will allow alternate input formats like:

.. code-block:: text

    216f-ff40-98d9-11e3-a5e2-0800-200c-9a66
    {216fff40-98d9-11e3-a5e2-0800200c9a66}
    216fff4098d911e3a5e20800200c9a66
