  - DocumentPath
```
public DocumentPath(String nodeName,
                    DocumentPath parentPath)
```
    Constructs a new document path.
    New paths must contain at least one name and string names MUST NOT contain any path separator characters. If one field is null that field will be ignored.
    
    Parameters:
    
    nodeName - the name of the last level of this path
    
    parentPath - the path representing the parent leading up to this node, in the case of the root this should be null
    
    Throws:
    
    IllegalDocumentNameException - if both parameters are null or name contains an illegal character ('.')
