I'm sure that WSDL 1.2 will be the most beautiful spec ever and solve all of
our description problems.  But there are some widely deployed WSDL 1.1
systems out there that it would be nice to be able to do RM with.  Customers
often don't like to be told "Please wait for n years".

Out of curiousity, what would you see being a better way of not mixing the
architectural layers in a 1.1 environment?
