Personally I see it as the other way around; it was a mistake to
suggest that the MIME type and the document itself are inseparable.
What has such an approach gained us over the years? Certainly not

XHTML 1.0 was incredibly important for HTML because it told people how
to generate XML documents that could be rendered in web browsers. In
other words, the world of XML tools could be used to generate
documents, and yet those documents could still be read in standard

But why insist that browsers must interpret those documents as XML?
For example, sending a non-well formed XHTML document to Firefox means
you get a blank page with lots of hyphens and a caret...what use is
that to anyone? And worse, it goes against the whole history of HTML,
where attempts are made to render documents that have errors in.

Of course, the HTML 5 route, of trying to recover from every error is
in my view, just as bizarre, but that doesn't really matter. The key
point is that there should be nothing wrong with creating a document
using XML tools, and then delivering that document to an HTML
rendering engine and seeing something useful.

That's what most of the world is doing, after all.
