Misleading/incorrect statement in Opus codec registration

[Vanilagy]

The Opus codec registration states the following:

The conclusion I draw from this is that when description is set, the bitstream is in the 'ogg' format. However, this is not necessarily the case. description may still be provided even if the format is 'opus', and the 'ogg' format may not even be supported even if description is being set.

Here's a repro link: https://jsfiddle.net/7d1fLmbz/4/
I'm on Chrome Version 131.0.6778.86 on Windows 11.

I think what the registration is meaning to say is that each user agent is free to set description if they want, it's just when they set it it needs to be an Identification Header. It's very useful that it does this and I make use of this description field myself. However, the presence of description cannot be used to conclude whether the format is 'opus' or 'ogg'.

Yes this needs a bit of work, I don't think this was ever implemented by any browser, per spec, we might want to change the spec.
