Subject: RE: [cgmo-webcgm] MIME Media Type for ECMAScript
Lofton, I'm glad that you got the HTML attachment the first time around. However, the HTML attachment did get lost in the OASIS archived copy of the message. In my resend, the HTML simply got appended to the end of the message in the archived copy. This is an example of software being too smart for its own good.

All -- please give some attention to the last paragraph of Rob's original message, especially: "Does anyone know of a setting that enables IE 7 or 8 to recognize the application/ecmascript media type?"
