If such a handler is defined for a subscription then this candler is called from the DataBind server callback handling in place of the default handling. The DataBind server callback handler does the Invoke handling for Windows thread synchronization and then calls this handler for each item in the server callback.
The handler is true if the item is handled. Otherwise the default DataBind server callback handler will try to handle the callback for this item.
