DomXML and Zend Engine 2

Hi, I'm testing the last php5/ze2 snapshot for a future PHP application. I've a two line script[1] with domxml wich fail with ZE2 but succeed with ZE1. I know that ZE2 is in pre-alpha cycle (and domxml on a experimental state) and I'm not crying to have something functionnal but I've some questions : - is it a bug of a "should work but it is still experimental so it may be a bug" ? (and then I fill a bug in the bug database) - or is it a bug of a "we are working on port to ZE2" state ? (if yes : should I fill the bug in the database ?) - or simply a "not compatible and no work planned to make it compatible" ? This answer will help me to planify the tests and evolution of my application. Thanks.
