Does anybody know about a windows clipboard flavour name for FLAC in use?

Hi all,

As some of you might know, the FLAC format is being processed by an
IETF working group to become an internationally recognized standard.
Part of this process is FLAC being assigned a media type (also known
as MIME-type by many): audio/flac. However, during review of the
application, it was requested to include a UTI and a Windows Clipboard
Flavour Name.

Now, apparently the latest macOS already includes a UTI for FLAC as
one of its core types, apparently that is org.xiph.flac. If anyone can
confirm that, that would be great.

Finding any Windows Clipboard Flavour Name (see
https://learn.microsoft.com/nl-nl/windows/win32/dataxchg/clipboard-formats)
already being in use by any program seems harder. As there are a lot
of devs around here, does anybody know of any Windows program allowing
copying/cutting/pasting of FLAC data? If so, what is the name being
used to designate the clipboard contents?

If no-one knows of a name already being used, I suggest using
audio/flac. Apparently for at least jpeg, gif and png, media types are
also being used as clipboard format names/flavour names.

Kind regards, Martijn van Beurden
