The standards have always been a bit more abstract than you use in practice. Common practice prior to this would be /catsearch?sleep=20&sunbeams=yes&breakfast=0300 where the "resource" is /catsearch and the rest are query parameters, but you could also use /catsearch/sleep/20/sunbeams/yes/breakfast/0300 which looks like a "resource", but nobody is actually enforcing that it is a "resource".
