Defining an XML model

Model Preview page

The Preview page of the model property sheet displays a preview of the

XSD, DTD or XDR file generated from the XML model.

Example of an XSD file (or schema file):

The schema file starts with the XML declaration followed by the <schema> (root element) declaration.

All objects created in the model will appear in the schema file between the schema start-tag and end-tag.

Creating an XML model

There are several ways to create an XML model:

♦Create a new XML model

♦Create a new XML model using a template

♦Create an XML model using existing elements (reverse engineering an XSD, a DTD or an XDR file, generating from a PDM or an OOM)
