Name conventions for the zone population function

Where zoneid is case-sensitive and can contain alphanumeric or the underscore characters only. Do not use spaces or any special character other than underscore. This ID is used across the application. It is sent in each recommendation request to indicate which zone to use for the request. The page developer who encodes the recommendation request needs the configured zone ID for each active zone on the site. This zone ID is the same value that is used when you are defining the zone with the IBM® Digital Recommendations user interface.
