Throughout this discussion where I've been saying "URL" I've really
meant "HTTP URL".
YADIS won't work on a mailto: URL because you can't retrieve it to
discover its capabilities. The operation "retrieve" doesn't make any
sense on mailto:, since it's not really a protocol.
In theory you could use an ftp: URL, since you can retrieve a capability
document from that, but support for FTP and other protocols is much more
of a burden to put on consumers, and the document as it currently stands
depends on some HTTP-specific things such as the Content-type of the
(and when I say "HTTP URL", I'm also including "HTTPS URL", since HTTPS
is of course just HTTP over SSL.)
