Modifying BIND's version string

I'm trying to modify BIND's version string by inserting the following into named.conf:

options { version "text";
};

I save and try to restart BIND, but it fails. Everywhere I've looked suggests I have the correct format. Am I missing a step here, or do I in fact have the wrong format?

Any suggestions much appreciated.
