Your problem report is not all that clear.  My understanding is that
you want browsers who send zh-CN in their Accept-Language to get pages
with the .zh-CN extension, but you want browsers who send zh-TW to get
pages with the .en extension.  This could be accomplished by marking
the .en pages with two different languages, but I don't believe apache
supports that.

I see two ways to handle this:

1. create a duplicate copy (or even better, a symlink of) the .en page
with the .zh-TW extension and use the standard
AddLanguage zh-TW .zh-TW
config.  You'd be lying to the clients about the language, but that
shouldn't be a big deal.

2. Eliminate all references to zh-TW in your config and use
LanguagePriority Prefer Fallback (available only in 2.x)
(and make sure en is high up in your LanguagePriority)
