Root class for all the collection objects in this list:
a wrapper class on the GenericObjectList class for lists of objects
that can appear in NetObjects.
The resource identified by the request is only capable of generating
response entities that have content characteristics not acceptable
according to the Accept header field sent in the request.
The response has the same meaning as 606 (Not Acceptable), but only
applies to the specific resource addressed by the Request-URI and the
request may succeed elsewhere.
