//
// This file contains the definition of the srVisitor and srVisitorMgr classes.
//
// srVisitor
//      srVisitor defines the visitor interface class for the sr classes. The
//      application can derive this interface to implement a specific operation
//      on each of the concrete sr classes.
//
// srVisitorMgr
//      srVisitorMgr implements a manager for the visitor classes. This class
//      needs to be created and initialized by the application by registering
//      a derived visitor for each application defined schema representation
//      classes within an sdNameSpace.
