```
public interface DescriptorElement
```
Base element definition to reflect meaningful Impex header structure. For instance A|B,C(D[lang=en]|E)
To use this class you have to check for the concrete implementing type:
- ValueElement: Represents low level element in the structure. For instance: A(B).
- AlternativeListElement: Represents alternatives collection. For instance: A|B.
- ChildrenListElement: Represents lists of elements. For instance: A,B.
```
 Usage:

 
 DescriptorElement element = ...;
 if (element instanceof ValueElement) {
    // some action
 } else if (element instanceof ChildrenListElement) {
    // some action
 } else if (element instanceof AlternativeListElement) {
    // some action
 }
 
```
