For me, "fd" = "file descriptor" as defined by the operating system.

This is exactly what DBusFile.Handle property does: it opens the file 
and return the system file descriptor on it.

Then this file descriptor is put in the "attachment_fds" argument of 
desktop portal ComposeEmail() mail.

But as you noticed, it does not work.

I didn't found any documentation, nor any example, so it's hard to guess 
what to do without looking in all desktop portal implementations source 
code.

The difficulty is that the file descriptor is local to a process, so the 
desktop portal cannot use it with internal magic (it's possible to 
"send" a file descriptor to another process on Linux).
