The extension is irrelevant (according to the specs) and even in IE
where it is used as a hint as to the mime type, it's the mime type
that's more important.

The XML declaration isn't a PI and it wouldn't mean anything in a DOM
anyway as its main purpose is to specify the encoding used in a
linearisation of an XML document so has no meaning in a tree model where
all characters are unicode.

again mime types don't really mean much by the time you have an 
model in memory.

it's true you can say that, yes.

By the time that it gets to the renderer, IE needs html and mozilla
needs xhtml, the pmathml.xsl or auto-detect doctype solutions work by
the server serving xml and IE internally transforming that to html.
The js mechanism works the other way, with pages being served as html
and mozilla transforming to xml. neither mechanism changes the basic
rendering behaviour. It's like saying 
  "<p>hello</p> produces a paragraph that says hello"
That statement is basically true even though it's easy to generate
documents served as html or xhtml together with javascript or xsl or
even css that makes the actual rendered result say something else.
