+/**
+ * Interface for inquiring whether features are supported on the device.
+ *
+ * The code segment below shows an example of how the QuerySupport() API 
+ * should be used in client code that checks feature status. 
+ *   
+ * @code
+ *  
+ *  // Single query 
+ *  // 
+ *  TBool haveUsb = RFeatureRegistry::QuerySupportS(NFeature::KUsb) > 0;
+ *  if (haveUsb)
+ *    { // ... connect to USB service ...
+ *    }  
+ *
+ *  // or Multiple queries
+ *  // 
+ *  RFeatureRegistry featReg;
+ *  const TBool opened = (featReg.Open() == KErrNone);
+ *  iHaveUsb = opened && (featReg.QuerySupport(NFeature::KUsb) > 0);
+ *  iHaveBluetooth = opened && (featReg.QuerySupport(NFeature::KBluetooth) > 0);
+ *  featReg.Close(); // can always call Close(), even if Open() failed:
+ *  // ... proceed to update application menus based on these featue flags
+ *  
+ * @endcode 
+ *  
+ * Note the QuerySupport() API can return a negative error code. Clients 
+ * calling this API need to decide if this should result in specific error 
+ * handling or whether ignoring the error and assuming the feature is not
+ * supported is the best policy.
+ * 
+ * @see RFeatureRegistry::QuerySupportS      
+ * @publishedPartner
+ * @deprecated
