/**
 * QMan resource metadata exchange.
 * We cannot resuse the preexisting classes directly because the wsdl of the service instance
 * is retrieved using a file path.
 * Since the owner resource (QManWsResource) is dynamic (I mean, its interface is dynamic), the corresponding
 * WSDL cannot defined at compile time but needs some changes when the resource is created.
 * As part of that, the WSDL template found under wsdl folder is modified with the additional properties of the given 
 * resource. The metadata exchange capability must include those properties too.
 * 
 * Note that this capability is appliable only to a QManWsResource.
