OK. I see your point.

Generally, yes. However, I think xml:lang is so special. Suppose that
someone wrote Seaside app (Wiki, Blog, etc) in English, and one
Japanese would like to run it for Japanese users.
Basically, he would like to do just 2 steps:
-provide a new Japanese message catalog for the app
-set the app's locale to Japanese
If he is a good-skilled Smalltalker, it would be easy to do an extra
step - subclass WASession and override #updateRoot:. But, if he is
not, he might give up.
Moreover, if the app already uses WASession subclasses for switching
databases (Magma, GOODS, etc). We need to subclass them all, (and need
to override #updateRoot: redundantly).
More badly, if the app is commercial and he cannot access to the
source code, it would be impossible to localize. Currently, most
applications allow us to localize without accessing source code. So,
it is not so cool.

Yes. But, in most cases, just setting one default lang would be OK.
Suppose Wiki or Blog again. The users typically write contents in
their mother tongue. The application is universal, but in deployment,
the contents are localized. Of course, by subclassing WASession, we
can dynamically change the xml:lang by each session basis. But it
seems to be over-engineered for localized sites. Balancing the
flexibility and handiness, I prefer the config approach.
