+- `cardinal` and `ordinal` – Arrays of valid plural categories for the current

+  'one', 'two', 'few', 'many', 'other'`. To disable this check, pass in an empty

+- `strictFunctionParams` – By default, function parameters are split on commas
+  and trimmed, so the parameters in `{x,fn,   a,   b   }` are parsed as
+  `['a','b']`. Setting `strictFunctionParams` to true will make the parser
+  follow the ICU MessageFormat spec more closely, and result in a params array
+  with a single element: `['   a,   b   ']`.
