I am attempting to generate a client that calls a web service. I was able to get it nearly working, except it seems that the main method being called ends up with a tag with an xmlns attribute (i.e. <inv:InventoryUpdateBatch xmlns="...">). This is causing it to fail with "org.apache.axis2.databinding.ADBException: Unexpected subelement".

I know that removing the xmlns parameter on the main method's tag will work, as I confirmed it using SoapUI, by using the identical XML generated by SOAP::Lite, and removing that one xmlns attribute. Note that I am using call() to add a prefix (inv) to the method. That prefix is the same namespace that is in xmlns, which was previously serialized using register_ns(), so it shows up as an attribute on the soap:Envelope tag, xmlns:inv="...".
