Hello:
        Recently I meat a problem, that I should write a sca client program
which according to a dynamic xml description input to invoke the sca
component's service in a SCADomain?
        So does Tuscany support this feature  that could using xml-like
description to invoke service? Or is there any suggestion to me about how to
modify the source code of Tuscany to support this feature?
        
        Thanks to any suggestion
