+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, trailing underscores have special meaning for referencing, thus
+`code`:example:_ is considered to be an error:
