Enclosure directive for reStructuredText

Good afternoon.

Should reStructuredText have a directive for enclosures?

It is possible to scan HTML code for potential attachments (e.g.
torrent, ipfs, magnet, ogg, etc.), yet it might be better to have an
explicit directive to indicate of a media which is intended to be
realized as an attachment.

Perhaps a value for attribute "class" would be more appropriate.

Please advise.

Kind regards,
Schimon
