  - acceptVisitor
```
public void acceptVisitor(ProductVisitor visitor)
```
    Accepts the given visitor. This method implements the well known 'Visitor' design pattern of the gang-of-four. The visitor pattern allows to define new operations on the product data model without the need to add more code to it. The new operation is implemented by the visitor.
    The method simply calls visitor.visit(this).
    
    Specified by:
    
    acceptVisitor in class DataNode
    
    Parameters:
    
    visitor - the visitor
  - createDeepClone
```
public MetadataAttribute createDeepClone()
