OK, thank you. All of this suggests scheduling further discussion, but I 
note Larry that you've sent regrets for this week. Should we wait until 
you're available (I'll leave this off the agenda for now, but will add it 
if you suggest it's urgent). Thank you.

I raised these in the much earlier "mime-web-info" draft, but the only feedback I got from the media-type-regs editors was that my document was "not helpful".    If the TAG has been successful in articulating issues in a way that they get some attention, perhaps we could also talk about:
> File extensions:
>     File extensions are part of the web. They're not part of http (because the trailing end of the URL could be anything), but they're part of "ftp:", they're also part of shared file storage systems like DropBox and Google Drive as well as older file sharing systems like NFS. They're relevant to HTTP and HTML:  The HTML working group added a feature in file upload dialog boxes to ask for file extensions, for example.  (Should we look at webarch and shared drive systems?)
> The MIME registry includes a place to list "file extensions", but there are no good practices listed for choosing file extensions or using them, and the registry doesn't "match reality".
> Magic Numbers:
> The MIME registry includes a "magic number" section without a lot of guidance to put in it. The current registry doesn't match what systems use (for detecting fingerprints), the (inactive) MIME sniffing document contains its own table of magic numbers.  Again, I'm not sure what shared cloud storage drives do with file extensions or conversions.
