<args_t> is a table of parameter name/value pairs. Parameters that are supported are:

args_t.italic - accepts string values 'no' or 'off'; {{lang}} expects 'no' so 'off' must be translated

args_t.nbsp - accepts 'omit' or 'no'
args_t.parensize -

add support for romanization and transliteration?
add support for postfix so that 'mis' can render something like this:
