¶ Source
To view the representation of the structure of the DCC schema or DCC XML files we use different software tools. In this DCC Wiki we have mainly used Oxygen XML Developer1.
¶ Nomenclature
¶ Frequency of elements
XML elements can occur different times. To do this, XSD Diagram uses the option the following nomenclature:
| Cardinality | Graphic |
|---|---|
| exactly one |  |
| one to unbounded |  |
| 0 or 1 |  |
¶ Child elements
If an element has child elements, there is a button on the right side with a "+". If you click on the "+" button, you will see the elements of the next level.
| Child elements | Graphic |
|---|---|
| collapsed |  |
| expanded |  |
