And here. Wonderful. So, given some random text page, with no other
labelling, then yes, you would need to guess. And there are ways to do
so. No way to tell if you guessed right.

With XML, having made a determination of what the encoding is, it can
instantly be verified, because the encoding declaration is required. So,
the label is there all along, is absolutely required to be there
otherwise it is a fatal error, and all that is needed is a little
bootstrapping. This is clearly not the same thing as the previous case,
at all.
