Language Titlecasing

We've struggled with how to handle the titlecasing of language names. Here's a proposal.

Background

There are three main ways to present languages in a menu or list. Here are examples, presuming that the native language of the user is French.

For example, the Self approach is used on http://translate.google.com/?hl=fr#. http://fr.wikipedia.org/wiki/ (titlecase) and on http://www.facebook.com. The Native approach is used on http://www.google.com/language_tools?hl=fr.

One of the problems with the Self approach is that the casing gives a ransom-note effect, so we see wikipedia and facebook both using titlecase consistently.

However, we have not wanted to ask all translators to supply both a normal and titlecased variant of language names. What I suggest we do is ask the translators in the ST to supply an alt=titlecase version of languages names in just some restricted cases, when the normal language name:

1. is the name of itself. (Français, Deutsch, Suomi)
2. is cased. (excluding Japanese, Chinese, etc.)

Once we have this, people who want to use the Self approach can do so with consistent case, as in the following:

BTW, in the above lists, the Self lists are sorted with a neutral sort (UCA-CLDR), while the others use the user's language. It is, of course, possible to use the user's language for sorting the Self list; but typically the Self list is constant across languages, so the neutral sort is better...
