Description

I suggest the ability to store arbitrary data in line with single attachments to a doc. The mooted use is to store metadata about that attachment.

For example, a current attachment:

m['_attachments']
=> {"yamanote.jpg"=>{"content_type"=>"image/jpeg", "stub"=>true, "length"=>382613}}

Desired behaviour is to be able to insert persistent metadata like so:

m['_attachments']
=> {"yamanote.jpg"=>{"content_type"=>"image/jpeg", "stub"=>true, "length"=>382613, "width" => 800, "height" => 600, "md5" => "95de7a118ee28824afa8d2ad8fe5819f"}}

And many other use cases according to media type.
