You know Shift-Ctrl-v in OOo proposes you a list of formats before
pasting, just select plain text there.

If I may explain how BeOS and Haiku do, that can surely give hints.
In BeOS, and Haiku, we already use mimetypes for the clipboard, see
For text there should always be a text/plain version, and applications
supporting it add the BeOS-specific text formating data, and sometimes
DnD protocol in BeOS also propose a set of mimetypes for the data,
either directly or via a file, which the target can accept or not.
I don't know much about X11 clipboard formats, but it should be
possible to stuff several mime versions inside.

That's exactly what BeOS and Haiku do on drag-n-drop, mainly for
images. They build a list of translators that supports the native
format on input, and the target displays a list of formats (PNG, JPG,
...), usually only on right-button drags, left drags selecting the
default native format.

Is application/mbox standardized at all ?
If not it should really use x- prefix, and to me the basetype should be
BeOS uses "text/x-email" for mail files (that is, in a maildir-like
format, but with xattrs).

Yes, Ctrl-Shift-v does in OOo.

I suppose Gnome and KDE have datatypes like engines already, are they
