-- elements as follows:
-- * `extra_specs`: An optional table of extra key-value pairs to add to the spec used for parsing the parameter
-- when specified as a separate parameter (e.g. {type = "boolean"} for a Boolean parameter, or
-- {alias_of = "t"} for the "gloss" parameter, which is aliased to "t"), on top of the default, which
-- is {list = true, allow_holes = true, require_index = true}.
-- * `convert`: An optional function to convert the raw argument into the form passed to [[Module:affixusex]].
-- This function takes three parameters: (1) `arg` (the raw argument); (2) `inline` (true if we're
-- processing an inline modifier, false otherwise); (3) `i` (the logical index of the term being
-- processed, starting from 1).
-- * `item_dest`: The name of the key used when storing the parameter's value into the processed `parts` list.
-- Normally the same as the parameter's name. Different in the case of "gloss", which is an alias for
-- "t".
