Description

When multipart RFC822 emails are being parsed, there's no way to distinguish between alternative versions of the body and attachments.

It would be ideal if some kind of flag were set in the metadata passed to the EmbeddedDocumentExtractor that indicates that the stream is an alternative.

In GUIs that present the data extracted from the email, alternative bodies can be distinguished from attachments and presented separately.
