I've read a lot of criticism to WADL (see for example http://bitworking.org/news/193/Do-we-need-WADL),
since it could lead to something like WSDL/SOAP/RPC/Berlusconi & other human's fault.
Actually a wadl file should have it's own mime type (does it have one?) but it seem quite good as hypertext language as far as the client can handle it (through, for example, some code on demand).
I'm not considering it a tool to generate such code (even if it would be possible, and as far as the code is downloaded with the wadl, still restful), but just a simple and clean way to connect the resources.
It seem to me that nothing restfully wrong to use an alternative hypertext language instead of html, isn't it?
