/**
* 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.
