+RST uses single backticks or back-quotes for various things including
+interpreted text roles and references.
+
+Without a semi-colon prefix or suffix, `example` has the default role.
+A prefix like :code:`example` or a suffix like `example`:math: is allowed.
+
+However, :code:`example`:math: with both prefix and suffix is considered to be
+an error and should fail validation:
