literal encoding style for JAXRPC Call ??

[Mark D. Hansen]

I understand that to force a Axis Call instance to use the Literal XML encoding, you 
can us this command:

  call.setEndocingStyleURI(Constants.NS_URI_LITERAL_XML);

Is there a JAXRPC compliant way to do this?  I assume that you can use 

  call.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY,
                   Constants.NS_URI_LITERAL_XML);

But this still uses the Apache-specific constant Constants.NS_URI_LITERAL_XML = 
"http://xml.apache.org/xml-soap/literalxml";.  It seems to me that we need an 
equivalent of JAXRPC NamespaceConstants.NSURI_SOAP_ENCODING for the Literal XML 
encoding.  Am I missing something?

Thanks,

Mark
