+class CReferenceDefaultSubConnectionProvider : public CSubConnectionProviderBase, public MConnectionDataClient
+/** 
+CReferenceDefaultSubConnectionProvider is a reference implementation for a shared subconnection,
+that is: either 
+* a subconnection explicitly requested by a client openning an RSubConnection in EAttachToDefault mode
+* an implicitly created shared subconnection.
+Typically reserved and shared subconnection providers, although represent the
+same layer/technology, require different implementations of CSubConnectionProviderBase. 
+This example code takes that into account and provides two separate classes for reserved and 
+shared subconnections respectivelly. Should the implementation differ little or not differ at all,
+developers are encouraged to introduce inheritance between the two types or implement just one
+universal CSubConnectionProviderBase subclass, if sensible.
+The following should be read like a class diagram for a CSubConnectionProviderBase:
