    corresponding bodypart formatter, and the result inserted into
    the bodypart formatter factory.

    Subtype alone or both type and subtype may be "*", which is
    taken as a wildcard, so that e.g. type=text subtype=* matches
    any text subtype, but with lesser specificity than a concrete
    mimetype such as text/plain. type=* is only allowed when
    subtype=*, too.
