There is a review of xsd.exe here that explains that xsd.exe creates XML Schema documents (XSDs) .. This message contains the announcement (a year ago) about the tool, but all xsd appears to do is assist in validating XML.

How does that relate to your question about something that generates Perl code? Would the Perl code be a factory object that would generate objects according to an XML schema? Do you have links to the Java and C# translations you've mentioned?

We need more information before we can offer any solutions.
