Technically, the "identifier" is still the URL, but the request parameters
dictate which XRDS is returned. All the XRDS documents describe the same
logical resource, they just give you different logical views of its
XRI resolution works the same way. Using XRI reference processing (the
xrd:Ref element), if you ask an XRI resolver for a certain type of service
endpoint for an XRI, you may get back a different XRDS than if you asked for
a different service endpoint. They all describe the same resource, but just
from the viewpoint of different authorities.
