How can I set the Implementation of this Document?

How can I set the Implementation of this Document? Actually, I just want to save a property in the Document or read a property from the Document's Implementation. Ever since PHP 8.2 deprecated dynamic properties, I've been waiting for a solution. For years, I've been using hooks.

`

new class extends DOMImplementation
{
	public readonly string $token;
	public readonly DOMDocument $document;
	function __construct()
	{
		$this->token = 'mytoken';
		$this->document = $this->createDocument(NULL, 'html', NULL);
		var_dump( $this->document->implementation ); //Why is this not created by my custom class implementation?
		var_dump( $this->document->implementation->token ); //I just get this property like this

	}
};
