report=The validation service simply does not forget the previous state of the URI, even when Clear URI is pressed several times. By chance the server for http://msc2010.org/mscwork/msc2010-draft3.skos was down a while ago. Now the ISP has got it back up. I still cannot get the URI checked. A similar thing happened last night where the first pass found a small error. I fixed it and uploaded an amended version, and the checker kept reporting on the old version which I could see was not at that URI by editing the file. ion AT ams.org. In fact I had this problem in July but did not complain at the time.
