DOMDocument::registerNodeClass manual contains the following chapter:

"Example #3 Retrieving owner document

When instantiating a custom DOMDocument the ownerDocument property will refer to the instantiated class, meaning there is no need (and in fact not possible) to use DOMDocument::registerNodeClass() with DOMDocument"

In fact this information is wrong. DOMDocument::registerNodeClass() with DOMDocument is required to set to work with extended DOMDocument classes

Otherwise extended DOMDocument class will be changed to unextended DOMDocument on context change

Please look at:
Bug #60323
Extended DOMDocument will change to unextended DOMDocument on context change

Right; but example #4 (Custom objects are transient) is still
correct, and needs to be considered by the developer.
