[X3D-Public] [x3d-public] model/x3d+xml is not registered

There may be a few issues here.

First, you want your server to serve the approriate mime for the file 
suffix. .
This is important because the X3D browser typically claims various 
mime(s) association with the file suffix(es).

1. the mime model/x3d+xml is working fine for browsers that register 
the type at installation, then click or embed .x3d file plays as 
expected..
2. the mime model/x3d+vrml is held due to registration doesn't like 
the + symbol.
3. the mime model/x3d-vrml is in limbo.
4. the utf-8 character encoding now allows an optional utf-8 BOM while 
X3D VRML Classic encoding and legacy VRML expects only the # symbol as 
the first character..
This buzzed the html browsers for a while but now they all accept the 
optional utf-8 BOM. I'm not sure how each X3D browser handles the 
optional utf-8 BOM.

So, learn what the X3D browser claims at installation then tell your 
server to serve the files with the appropriate mime.

Guidance is currently at:

http://www.web3d.org/x3d/learn/mimetypes/

and at:

http://www.web3d.org/x3d/specifications/OLD/ISO-IEC-19776-1-X3DEncodings-XML/Part01/concepts.html#FileExtensionAndMIMETypes

In general when serving the file with a mime type not recognized and 
matched with a file suffix may cause a simple load rather than a load 
and execute. I think the advantage of having the mime "Registered" 
officially is then the server configuration may handle server updates 
'automatically' from the official list instead of you creating the 
.htaccess file manually on your server.

Good Luck and All the Best,
Joe

It seems nothing has changed in the five years since I sent that mail.
Is there any help anybody could offer to get a type for X3D registered
or are there any recent developments in this area that I am not aware
of?
