I too recall the debate about WAV.
The specification developed by IBM and Microsoft on the WAV , RIFF
format is:
"Multimedia Programming Interface and Data Specifications 1.0, Resource
Interchange File Format, Waveform Audio File Format (WAVE)", IBM
Corporation and Microsoft Corporation, August 1991
There is also an addendum/update document by Microsoft:
"Multimedia Standards Update New Multimedia Data Types and Data
Techniques" April 15, 1994 Revision: 3.0
So there is a clear published WAV standard. It seems the problem is,
some implementations do not follow the specification. I believe any
reference to the format of a WAV file should refer to these published
documents. Maybe you can refer to them as reference documents in the
draft in informational form.
I agree there are many incompatible implementations of WAV file creation
and parsing on the market.
Media players, such as RealPlayer for example, have troubles with MS-GSM
WAV files. The QuickTime player on Macintosh is another one that has
troubles with MS-GSM (although I have not tested the latest versions of
these players for a while).
It will be great if the IVM efforts can nudge the main media player
manufacturers and software implementations to follow the standards,
allowing interoperability.

I co-authored a draft a while ago. There are some errors that need to
be
corrected. Due to a lack of a clear published WAV standard and multiple
incompatible implementations on the market, I believe that both this
draft
(in informational form) and the IANA registration will be necessary.
