Hi Ted,

In the future, please send questions about XSD/e to the xsde-users

Well, it is what the error message says. The --generate-test-driver
option generates a test driver that parses/serializes a document
with a specific root element. If the schema has only one global
element, then it is assumed to be the root element. If the schema
defines multiple global elements, then all of them are valid root
elements and the above error is issued. To resolve it, you can pick
a root element that you want the driver to use and specify it with
the --root-element options.
