<P>
MultipartDataSource is a <code>DataSource</code> that contains body
 parts.  This allows "mail aware" <code>DataContentHandlers</code> to
 be implemented more efficiently by being aware of such
 <code>DataSources</code> and using the appropriate methods to access
 <code>BodyParts</code>. <p>

 Note that the data of a MultipartDataSource is also available as
 an input stream. <p>

 This interface will typically be implemented by providers that
 preparse multipart bodies, for example an IMAP provider.
