<args_t> is a table of parameter name/value pairs. Parameters that are supported are:
args_t[1] - IETF language tag (required)
args_t[2] - the native name (required)
args_t.italic - accepts string values 'no' or 'off'; {{lang}} expects 'no' so 'off' must be translated
args_t.italics - alias of |italic=
args_t.paren - accepts 'omit', 'off', or 'no'
args_t.icon - alias of paren
args_t.parensize -
args_t.fontsize - deprecated alias of |parensize=
args_t.nolink - any value inhibits wikilinking of language name
this function calls these functions in Module:lang:
_is_ietf_tag
_lang
_name_from_tag
TODO:
add support for romanization and transliteration?
add support for postfix so that 'mis' can render something like this:
