This read-only string names a particular web-related service entry, in a table covering things like the general HTTP and HTTPS services and possibly the extra port, so it can be identified among multiple configurable web services on the device. An administrator reads this to know which row in the services table corresponds to which actual service before adjusting its port, protocol, or enabled status. For example, an admin looking to change the extra port's settings would first confirm this OID reads a name like 'extra' to be sure they're editing the correct service row.
