Hannes, None of the current OAuth WG document address discovery in any way, so clearly there will be no use of XRD. But the OAuth community predating the IETF had multiple proposals for it. In addition, multiple times on the IETF OAuth WG list, people have suggested using host-meta and XRD for discovery purposes. The idea that XRD was reused without merit is both misleading and mean-spirited. Personally, I'm sick of it, especially coming from standards professionals. XRD was largely developed by the same people who worked on host-meta. XRD predated host-meta and was designed to cover the wider use case. Host-meta was an important use case when developing XRD in its final few months. It was done in OASIS out of respect to proper standards process in which the body that originated a work (XRDS) gets to keep it. I challenge anyone to find any faults with the IPR policy or process used to develop host-meta in OASIS. XRD is one of the simplest XML formats I have seen. I bet most of the people bashing it now have never bothered to read it. At least some of these people have been personally invited by me to comment on XRD while it was still in development and chose to dismiss it. XRD was designed in a very open process with plenty of community feedback and it was significantly simplified based on that feedback. In addition, host-meta further simplifies it by profiling it down, removing some of the more complex elements like Subject and Alias (which are very useful in other contexts). XRD is nothing more than a cleaner version of HTML <LINK> elements with literally a handful of new elements based on well defined and widely supported requirements. It's entire semantic meaning is based on the IETF Link relation registry RFC. There is something very disturbing going on these days in how people treat XML-based formats, especially form OASIS. When host-meta's predecessor - side–meta – was originally proposed a few years ago, Mark Nottingham proposed an XML format not that different from XRD. There is nothing wrong with JSON taking over as a simpler alternative. I personally prefer JSON much better. But it would be reckless and counter productive to ignore a decade of work on XML formats just because it is no longer cool. Feels like we back in high school. If you have technical arguments against host-meta, please share. But if your objections are based on changing trends, dislike of XML or anything OASIS, grow up.
