"sftp" in port-numbers refers to port 115, with usage

And it's definitely no IANA registered URI-scheme like "tftp":
<http://www.iana.org/assignments/uri-schemes>
It's also not mentioned in an old and unofficial collection:
<http://www.w3.org/Addressing/schemes.html>
The latter is interesting for unregistered schemes like snews.
sftp as defined in draft-ietf-secsh-scp-sftp-ssh-uri-03.txt
defines an URI scheme, and doesn't need a separate port
number.
IMHO it should say which default port it's talking about for
the <port> part of <authority> in its chapter 2.2. If I got
this right the scheme "sftp" is also unrelated to the service
"ftps" (989 and 990).
I agree it's confusing, but it's not really a conflict.
There exist other "secure FTP" protocols, such as RFC 2228.
The sftp-draft could mention those "near misses". Bye, Frank
