This example demonstrates a common (and most unfortunate) modification to an
OFFICIAL [ObjectClass] definition -- "groupOfNames", found within Section 3.5
of RFC 4519.

The design of this particular class is widely considered to be inconvenient
due to its mandate that at least one (1) instance of the "member" [AttributeType]
(from Section 2.17 of RFC 4519).

As such, this has forced many LDAP architects to literally modify this [ObjectClass]
definition within the given directory schema, moving the "member" [AttributeType]
from the MUST clause to the MAY clause.

For reasons of oversight, we've added the RFC of origin as an X-ORIGIN extension, and
a custom extension X-WARNING to remind users and admin alike that we've resorted to
this risky trick.
