```
public class DefaultTagDescriptor
extends TagDescriptor<Directory>
```
A default implementation of the abstract TagDescriptor. As this class is not coded with awareness of any metadata tags, it simply reports tag names using the format 'Unknown tag 0x00' (with the corresponding tag number in hex) and gives descriptions using the default string representation of the value.
