[loc-en-dev] Prefix subtag used for ill-formed variant in private use

[Yoshito Umaoka]

Hi All,

In the latest design note, we use private use subtag "jvariant" as the 
prefix of ill-formed variant in BCP47 language tag representation. I 
would like to change this to "lvariant" (stands for l(ocale) 
variant...). The requirement of this is - any distinctive subtag which 
can avoid collision. "jvariant" and "lvariant" actually do not make much 
difference. I want to make it more generic, so want to use a latter 
other than "j". Any objections?

(Background: We also implement this in ICU and I thought "jvariant" 
looked funny for our C implementation. I think such workaround might be 
used for other locale implementations, not just by Java/ICU)
