### `scope`

The spec also says that the client can send another form field "`scope`".

The form field name is `scope` (in singular), but it is actually a long string with "scopes" separated by spaces.

Each "scope" is just a string (without spaces).

They are normally used to declare specific security permissions, for example:

        wrapperToPrimitiveMap.put(Byte.class, Byte.TYPE);
        wrapperToPrimitiveMap.put(Short.class, Short.TYPE);
        wrapperToPrimitiveMap.put(Integer.class, Integer.TYPE);
        wrapperToPrimitiveMap.put(Long.class, Long.TYPE);
        wrapperToPrimitiveMap.put(Float.class, Float.TYPE);
        wrapperToPrimitiveMap.put(Double.class, Double.TYPE);

        primitiveToWrapperMap.put(Boolean.TYPE, Boolean.class);
