  - apply
```
void apply(XPathContext context,
           int validationMode)
    throws XPathException
```
    Apply the pending updates

  - addPutAction
```
void addPutAction(NodeInfo node,
                  java.lang.String uri,
                  Expression originator)
           throws XPathException
```
    Add a put() action to the pending update list
    
    Parameters:
