The EBU document is a recommendation that is a bit outdated at this point. In my experience, implementation varies according to the needs and priorities of the digitizing organization. It is possible to enter whatever you want into the field but I think it should be part of a larger metadata plan that includes institutional specifications for embedded metadata as well as external metadata.

For the BEXT chunk, the highest bit depth permitted appears to be 24
bits. How does one code 32 bit fixed and 32 bit floating point? Are 32
and 32FP acceptable? Or 32Float?
Also, the standards for sampling frequency stop at 48000, but I assume
96000, 192000, and 384000 are acceptable.
