   1.114 +/**
   1.115 +  * The class for connecting to service providers
   1.116 +  * through Web Services Framework (WSF). 
   1.117 +  *
   1.118 +  * The class offers asynchronous construction of a
   1.119 +  * service connection. Further, there are asynchronous
   1.120 +  * and synchronous interaction methods for e.g. sending 
   1.121 +  * and receiving data from (possibly remote) service.
   1.122 +  * 
   1.123 +  * WSF offers two default frameworks:
   1.124 +  *
   1.125 +  *   1. Identity Based Web Services Framework
   1.126 +  *      (ID-WSF). The framework ID for this is 
   1.127 +  *      KDefaultIdWsfFrameworkID ("ID-WSF").
   1.128 +  * 
   1.129 +  *   2. Basic Web Services Framework. Framework
   1.130 +  *      ID is KDefaultBasicWebServicesFrameworkID
   1.131 +  *      ("WS-I").
   1.132 +  * 
   1.133 +  * The most typical use of CSenServiceConnection
   1.134 +  * is to interact with a service of certain type
   1.135 +  * through some invocable framework and submitting
   1.136 +  * and receiving messages.
   1.137 +  *
   1.138 +  * In case of WebServices, the actual service is remote
   1.139 +  * and submitted messages are SOAP envelopes. However,
   1.140 +  * CSenServiceConnection supports accessing any
   1.141 +  * ServiceInvocationFramework which ECOM plug-in
   1.142 +  * implementation is present. These plug-ins may
   1.143 +  * further communicate with some service, including
   1.144 +  * local services. 
   1.145 +  * 
   1.146 +  * The link between CSenServiceConnection and any plug-in
   1.147 +  * implementation interacting with some service is the
   1.148 +  * framework ID, which is a property of ServiceDescription (SD)
   1.149 +  * and accessible via MSenServiceDescription interface, which
   1.150 +  * each SD class must implement. 
   1.151 +  * 
   1.152 +  * When creating a connection, one offers predefined SD as
   1.153 +  * an argument for asynchronous constructor. Or, optionally 
   1.154 +  * only a Liberty Alliance ID-WSF specific contract string 
   1.155 +  * - typically some URN. If only contract is offered, then
   1.156 +  * the created connection defaults to ID-WSF service and 
   1.157 +  * ID-WSF framework (ID) will be used.
   1.158 +  * 
   1.159 +  * The WSF further uses the offered framework ID while looking
   1.160 +  * up any matching framework plug-in implementation. As a
   1.161 +  * result the SD might be offered to several plug-ins.
