Dear all, OpenOffice recently introduced language support for Valencian RACV grammar, using the nonstandard ca_XR language tag. This is presumably different from the AVL grammar (OpenOffice uses ca_XV) which also exists and already has two global LINGUAS: "ca_XV" that was at some point used by LibreOffice, but is now unused and replaced by the local flag "ca_valencia", and "ca@valencia" used by Calligra and others.
If I understand correctly, POSIX locales use language[_territory][@modifier] format, and the X in the "territory" is used to denote a non-standard extension. I am however unsure whether ca_XR is a correct use of "territory". Debian for example uses ca-ES@valencia for Valencian AVL, which appears to be based on the IETF BCP-47 (basically language[-region][-variant]) language tag ca-ES-valencia. Is it ok to add a ca_XR or ca@valencia-racv USE_EXPAND to LINGUAS or is there a better solution? Should LINGUAS try to imitate POSIX or BCP-47? Best regards, Chí-Thanh Christopher Nguyễn
