For example, if your extension is named "Very silly extension that does nothing", you might want to name all your configuration variables to begin  or. It doesn't really matter what you choose so long as none of the MediaWiki core begins its variables this way and you have done a reasonable job of checking to see that none of the published extensions begin their variables this way. Users won't take kindly to having to choose between your extension and some other extensions because you chose overlapping variable names.
