Tosca TBox supports XSD 1.0 files.
XML Schema definition language (XSD) files are used to define the structure of XML documents. This chapter includes a description of the supported XSD elements. How they are interpreted in XML modules is described in "Using XSD elements and value ranges". Several XSD files can be linked as described in "Linking several XSD files".

The table below lists all XSD elements. All XSD elements, attributes and value ranges, which are considered when an XSD schema is built, are marked in the Support column.
