Though I consider "mailto" an unfortunate misnomer ("mailbox" would have
been better), the "mailto" scheme is in no way fake. URI schemes do not need
to correspond to protocols; the "urn" scheme has no defined protocol. But if
we insist on correspondence to protocols as the measure of legitimacy,
"mailto" correponds to Simple Mail Transfer Protocol [SMTP] and the Domain
Name System [DNS].

I'm not sure what you mean by "link". I think that you mean a document, but
I'd like a clarification.

In my book, a link is an explicit specification of a relationship.

If you want the "mailto" scheme to lead to information, have your user agent
query the Domain Name System. For example, you come across
<mailto:user@example.net> and it leads to information from

That is one treatment, and perfectly valid.

If your user agent does not distinguish links using the "mailto" scheme and
you cannot configure your user agent to distinguish those links, that is a
user agent shortcoming.

I work with a similar shortcoming. My WannaBe browser does not handle FTP.
Any "ftp" URIs are passed to my default FTP application. Should we include
an FTP-designating element type so that WannaBe can easily distinguish this
