Extened Tags with WAV

When tagging a WAV file there are few Extended tags that work or that can be viewed. The file has RIFF and LIST data. How can I see this metadata in WAV files?

I do not have such wav files.
But perhaps you do.
Then take one of these and press Alt-T to see the extended tags and the field names in MP3tag.

BTW: this thread bears a certain resemblance to this one:
