XMI to XML Schema (XSLT Stylesheet)
These stylesheets translate XMI into XML Schema files. In particular, they allow to automatically generate schemata from AOM models that are represented in UML (see here). A first stylesheet translates the XMI file into a composite schema file. A second stylesheet splits this file into separate XML Schema files. The stylesheets require an XSLT processor with support for keys and output redirection such as SAXON.
