Description Shinya Kawanaka 2012-02-27 05:59:09 UTC 
It seems the spec does say anything.
I think HIERARCHY_REQUEST_ERR should be raised.

Are you sure we need to do anything here? ShadowRoot is a DocumentFragment (since it inherits from a DocumentFragment), and there's a  pretty clear algorithm of what should be done in DOM4 spec: http://dvcs.w3.org/hg/domcore/raw-file/tip/Overview.html#concept-node-append

I just thought appending a shadow root into an element seems something weird.
I understand the fact that ShadowRoot extends DocumentFragment, but I was thinking ShdaowRoot was a something special. It is not intuitive for me that we can do appending a shadow root.

But this is intentional, I try to understand why ShdowRoot is extended from DocumentFragment.
