MultipartDataSource is a DataSource that contains body
 parts.  This allows "mail aware" DataContentHandlers to
 be implemented more efficiently by being aware of such
 DataSources and using the appropriate methods to access
 BodyParts. 
Note that the data of a MultipartDataSource is also available as an input stream.
This interface will typically be implemented by providers that preparse multipart bodies, for example an IMAP provider.
