Hello, First of all, thank you very much for your time.
Since this is a free service I doubt they will be changing it soon, however, I will suggest this to them. This is one of the fixes I was refering to before: I downloaded the file and manually built a wadl with only one resources element. Also, I downloaded all of the referenced "xsd" files, and I compile the service in local. If you want these files to do some tests I will gladly send them to you, just let me know and I will attach them (or, if you prefer, I can just send as text the modified wadl resources section).

Can they have a single 'resources' with other ones collapsed into it as child resource elements ?
