This is actually a bad idea. If another application handles the type,
and wants to provide a custom icon for the mime type, and tries to
install it in the same place, we have a file conflict. See the related
mails from Alex L. to this same list, for a proposed solution, where the
MIME type XML file specifies a list of fallback icons to fall back
through.

Which spec says this? I was to understand that the MIME spec had been
changed to match the Icon Naming spec, as previously the MIME spec had
been suggesting what RoX did, which was different from both GNOME and
KDE on a large level.

Actually, it should be application-vnd.jdwg.{png,svg} in this case.
