 Whenever possible, you should include a code example that helps to explain the issue you are highlighting. Any code examples that you include should adhere to the following guidelines:
 
-*   The example should be less than 20 lines and ideally it should be runnable. If this is not possible, ensure that the example very clearly illustrates the issue that you are highlighting.
+*   The example should be less than 20 lines, but it should still clearly illustrate the issue that the query identifies.  If appropriate, then the example may also be runnable.
 *   Put the code example after the recommendation element where possible. Only include an example in the description element if absolutely necessary.
 *   If you are using an example to illustrate the solution to a problem, and the change required is minor, avoid repeating the whole example. It is preferable to either describe the change required or to include a smaller snippet of the corrected code.
 *   Clearly indicate which of the samples is an example of bad coding practice and which is recommended practice.

-*   Directly include the code as nested text in the `example` section, Use the `sample` block and define a `language` attribute to specify the language of the example:
