I feel that is a misunderstanding of the intent and the specification of Yadis.
This Yadis Specification provides:
A general purpose identifier for a person and
any other entity, which can be used with
a variety of services.
A syntax for a resource description document
identifying services available using that
identifier and an interpretation of the elements of that document.
A protocol for obtaining that resource
description document, given that identifier.
It seems clear from the spec that: If
http://example.com is an identifier for an entity
(for example, a party operating a web host), then
Yadis provides for using a Yadis document to
describe the services available using that identifier.
And, surely http://example.com can be used by
example as an identifier for itself. (And, by
the way, example can operate a web server at
example.com, that web server can provide
services, those services can be described in
a document that looks exactly like a Yadis
document, and that web server can serve that
document according to the Yadis protocol. Any
such document will actually be a Yadis document.)
