Exactly. In addition, LANG can be changed inside the document to
make multilingual documents possible. MIME "charset" is the same
for the whole document, without any problems.

Not that I am wiser about TEI, but I understand now a little bit about
"writing system declaration". (2) is not a problem at all, it is very
evident from the ISO 10646 characters in which scritp they are.
As for (3), TEI has a much different range of applications than HTML.
For example, transliterations may be very important because of
the possibility of including texts that have already been input
with some transliteration method. In the context of the WWW,
transliteration was also discussed, but mainly in the context
of helping a user that knows the language but not the script.
This is largely a client-side issue. As for character encoding
in general, HTML relies on HTTP and MIME in this respect, which
is very reasonable for an internet application, whereas TEI
had to or wanted to define its own stuff.
