hello john.

so i guess i was naive to just point to the iana list. could you point 
out some omissions of the iana list and the w3c list and some that are 
in none of both lists? i really would like to get an impression of how 
radically incomplete and detached from the Real World they are. thanks.

could you please point out a "uri scheme" that has been deployed this 
way (well-defined semantics bound to uris made available on specific 
http servers with well-defined dns names and some well-defined pattern 
to the uri's paths), i am really wondering where this has happened. and 
where it happened in a way that not just is done by some self-interested 
company, but instead in the way you were hinting at: some community 
effort which is not limited to just one server, and can be used by 
anybody interested in providing access to resources of the kind that are 
made available there. i honestly cannot think of such an example, but i 
am sure you do have something in mind.

thanks,

dret.
