PE 2015.2.2: node terminus doc mis-match

So, this doc [https://docs.puppetlabs.com/puppet/latest/reference/subsystem_catalog_compilation.html](https://docs.puppetlabs.com/puppet/latest/reference/subsystem_catalog_compilation.html) says node terminus can be one of 3 options: plain, exec, ldap.
However my install says node_terminus = classifier bug in doc ?
