Altova website: XML Schemas in UML
XML Schema diagrams display schema components in UML notation. Global elements i.e. elements, simpleTypes, complexTypes are shown as classes, or datatypes, with attributes in the attributes compartment.
There are no operations in the Operation compartment. The Tagged Value note modeling element is used to display the schema details.
For information about how the UML elements and XML schema elements/attributes are mapped, see XML Schema Mappings.
|Note:||Invalid XML Schemas cannot be imported into UModel. XML Schemas are not validated when importing, or creating them in UModel. XML Schemas are also not taken into account during the project syntax check. A well-formed check is however performed when importing an XML schema.|
