XSD Transformation

The XSD transformation converts Platform-Independent Model (PIM) elements to UML Profile for XML elements as an intermediary step in creating an XML Schema. Each selected PIM Class element is converted to an «XSDcomplexType» element.

Example

The PIM elements

After transformation become the PSM elements

These in turn generate this XSD
