anonymous wrote : such a part must refer to an element named after the operation How inportant is this requirement when deciding about unwrapping? This line does not indicate if it refers to the input or output messages? Unless they are different namespaces or the same element is referenced it is not possible for both to be named after the operation. Or is it sufficient for the name of the element to contain or start with the name of the operation? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3995163#...
