What about: Historically, uses of the DNS to map a domain name to a URL have relied on the NAPTR RRTYPEs and then on the DDDS [RFC3401] application framework with the DNS as a database as specified in RFC 3404 [RFC3404]. This has a number of implications such as the fact the RRSet returned will contain all URIs "connected" with the owner, and not only the ones related to a specific service. > There are several other editorial issues (e.g., "Querying for > URI resource records is not replacing querying..." later in the > Introduction and "Applications MUST know the specific service to > prepend..." in Section 3 (one cannot prepend "a service", only > an identifier of one)), but I hope we can leave them to the RFC > Editor to identify and sort out.
