 TableGen provides "bang operators" that have a wide variety of uses:
 
 .. productionlist::

 The ``!cond`` operator has a slightly different
 syntax compared to other bang operators, so it is defined separately:
 
 .. productionlist::
-   CondOperator: !cond
+   CondOperator: "!cond"
 
 See `Appendix A: Bang Operators`_ for a description of each bang operator.
