Regards. Iñaki, I understand the point David is making. DNS is something independant of WS and conversely. It is one way of resolving addresses, just like there will be people using hosts files. At no place the protocol specification dictates how a client should resolve a name to an IP address. The protocol specifies the transport part only. This is the same for other protocols. For instance, neither FTP nor HTTP explain how a client is supposed to resolve a host name, still the later explains how to parse a URI. DNS SRV is a DNS extension which only concerns resolvers. Not all clients will be using resolvers, just a part of them. Some others will simply forward the request to their HTTP proxy which will apply whatever DNS resolving method they know, including possibly DNS SRV. In practice, if there are new elements of DNS SRV that are specific to WS, they should probably be added to the DNS SRV spec and not the WS spec. Maybe the WS spec should mention that it addresses transport only and not address resolving. It may recommend to follow some principles to perform the resolving but should not specify how to do it. Hoping it's a bit clearer, Willy
