That's exactly why we need to activate IME there. If I understood his
comment, Kenichi is saying that we need to activate IME to type names in
Katakana while we need to deactivate IME to type in card numbers, etc... not
that website disables IME to restrict the input to Katakana.

I don't think we can limit it to pages with lang="ja" because I speculate
that most of Japanese websites don't specify the language. I'm quite
confused as to why you're so concerned about adding this property because
we're not changing the default behavior of WebKit by supporting this new
property. If anything, developers don't use this property and their
websites work as they do today. And if some websites decide to use
ime-mode, I'd expect them to know what they're doing. This might mean that
such websites won't work for users who don't regularly use CJK languages but
many of CJK websites don't target such users anyways.

only for Mac and Windows (or Windows only if we're so inclined) first until
we figure out what's correct on other platforms. I'm confident that there's
a way to support this feature in almost every platform with IMEs.

Yes, that's why I expect most of developers will not use this feature. As
MDC points out, this feature is for Web apps and alike that require heavy
localization; they don't target international users and i18n isn't a concern
I now tested, and it looks like Mac Firefox doesn't actually implement

As far as I checked on Firefox 4.0b6, it is implemented and works as
expected. Do you have a different version of Firefox?
