Re: [webcomponents] Shadow DOM and comment nodes (#411)

Well, if you still support CDATASection... that's semantically equivalent to Text. It would be very weird if CDATASection didn't end up in the flattened tree. And I guess the use for Comment / ProcessingInstruction is to hack around limitations of the DOM. Annotations that can be used for further processing as per OP.
