Just in the interest of completeness ... because I'm not clear that your
4 points cover it ...
It is important (eventually) to be able to change language "on the fly,"
in the middle of a document using a standard XML/HTML lang attribute.
One of the things we don't yet do well in assistive technology is
support multi-lingual texts. Of course the most glaring result is our
inability to support language texts -- the ones that try to teach you
another language. But, this is also a problem with history, sociology,
religion, literature texts, etc.
I would think we would eventually also want speech recognition
technologies able to understand two or more languages on the fly. One
user case might be a tool that drills you on vocabulary while you cross
