Hi --

  I notice we have the .wmz and .sub file extentions each defined twice
in trunk mime.types:

.wmz: application/x-msmetafile, application/x-ms-wmz

Couldn't tell you how those arise.  Should we really include
any non-registered types (x-foo) other than as commented lines
indicating what a sysop might want to support?

.sub: text/vnd.dvb.subtitle, image/vnd.dvb.subtitle

Bizarrely, both appear to be correct:

http://www.iana.org/assignments/media-types/text/vnd.dvb.subtitle
http://www.iana.org/assignments/media-types/image/vnd.dvb.subtitle

Anyone here active with IANA?  Looks like their mess!

That's per se not a problem (the same type and have multiple names, and file extension uniqueness is not enforced).

But what's weird is that the referenced spec doesn't even mention these types.

PS: yes, emailed IANA.
