    Ok got it working like a charm using "proxy pattern" with traits. The idea being declaring the common methods inside a "trait" in order for extended and registered Node Classes to have access even if not derived / child of the extended DOMNode…

    Here a small snippet :
    <?php
    namespace my;

    trait     tNode
    { // We need the magic method __get in order to add properties such as DOMNode->parentElement
    public function __get($name)
    { if(    property_exists($this, $name)){return $this->$name;}
    if(    method_exists($this, $name)){return $this->$name();}
    throw new     \ErrorException('my\\Node property \''.(string) $name.'\' not found…', 42, E_USER_WARNING);
    }

    // parentElement property definition
    private function parentElement()
    { if(    $this->parentNode === null){return null;}
    if(    $this->parentNode->nodeType === XML_ELEMENT_NODE){return $this->parentNode;}
    return     $this->parentNode->parentElement();
    }

    // JavaScript equivalent
    public function isEqualNode(\DOMNode $node){return $this->isSameNode($node);}
    public function     compareDocumentPosition(\DOMNode $otherNode)
    { if(    $this->ownerDocument !== $otherNode->ownerDocument){return DOCUMENT_POSITION_DISCONNECTED;}
    $c = strcmp($this->getNodePath(), $otherNode->getNodePath());
    if(    $c === 0){return 0;}
    else if(    $c < 0){return DOCUMENT_POSITION_FOLLOWING | ($c < -1 ? DOCUMENT_POSITION_CONTAINED_BY : 0);}
    return     DOCUMENT_POSITION_PRECEDING | ($c > 1 ? DOCUMENT_POSITION_CONTAINS : 0);
    }
    public function     contains(\DOMNode $otherNode){return ($this->compareDocumentPosition($otherNode) >= DOCUMENT_POSITION_CONTAINED_BY);}
    }

    class     Document extends \DomDocument
    { public function __construct($version=null, $encoding=null)
    {     parent::__construct($version, $encoding);
    $this->registerNodeClass('DOMNode', 'my\Node');
    $this->registerNodeClass('DOMElement', 'my\Element');
    $this->registerNodeClass('DOMDocument', 'my\Document');
    /* [...] */
    }
    }

    class     Element extends \DOMElement
    { use tNode;
    /* [...] */
    }

    class     Node extends \DOMNode
    { use tNode;
    /* [...] */
    }

    ?>
