This memo specifies that the existing MIME content-type 'multipart/alternative' should be restricted to cases where the alternatives differ in their content-type. When the alternatives differ in other properties than content-type, a new 'multipart/choices' content-type is to be used instead. This is necessary, because the present specification gives extremely bad downgrading for mailers not supporting use of 'multipart/alternative' for other differences than content-type. This memo also specifies a mandatory parameter to multipart/choices. This mandatory parameter will hopefully avoid the same problem occuring again in the future.
