Could you give an example of what you mean? Maybe we are misunderstanding
each other. I don't see how you can have any inline XML in text/html
<script> (except, I guess, if another script generates it using the DOM),
and ill-formed XML in an XML document causes the parser to abort long
before we get to the script processing.

(AST?) The whole point is that if the script is XML, there's no text to
parse -- it's already a DOM.

There's no XML there, at least not in the sense used by the HTML5 spec.
