I try to write a WSDL document by manipulating the Woden API but could not find the way to add an xml:lang attribute on a wsdl documentation element.
When I looked for the source of the DOMWSDLWriter class, I found that the printExtensibilityAttributes() and printExtensibilityElements() have been commented for reasons not really detailed.
In a previous need, I had to add specific nodes in the documentation element. I could have reached that point by creating a DOM Element with a fake root element, that I put as content of an instance of DocumentationElement. I though first that adding an attribute on my fake root element might have been a solution to print attributes on documentations, but it seems that this approach has not been considered. It seems to be a bug or did I missed something?
