He argues that XSD mapping to native is code (and back) is a source of
many problems, so if WADL encourages you to use XSD for a type system,
then you've made a wrong turn already.
I think I have to concur about the XSD side of things, it is something
to strongly discourage. Given the number of existing WADL documents to
be compatible with is zero, it may be time to push for it to be
relax-ng *only*. That is, if you expect WADL and the corresponding
types to be handwritten. If instead they get generated from some
service interface, then you are back in the same mess that we got from
reverse-engineered WSDL files.
Has anyone tried to write a WADL description for any modern service,
like Amazon EC2 REST API?
Interesting bit of pushback on WADL from Dare Obsanjano: http://www.25hoursaday.com/weblog/CommentView.aspx?guid=f88dc5a6-0aff-44ca-ba42-38c651612092 He argues...
