If you would like more help, please type "xsd /?".

The XSD file was copy/pasted from Appendix A in the following document: http://services.eoportal.org/portal/documents/06-141r2_Ordering_Services_for_Earth_Observation_Products_0.9.2.pdf

The XML Schema included in the PDF document you linked has references to several other XSD files using the <import> element. You will need to download these additional schema files and make sure that the path references in the <import> elements are pointing to the correct locations on your local computer.

If you are still getting errors, it is because xsd.exe could not follow up on external references. To solve this issue, specify all the required XSD files directly on the command line as follows:

xsd.exe /c MySchema.xsd Import01.xsd Import02.xsd Include01.xsd Include02.xsd

where Import01.xsd, Import02.xsd, Include01.xsd and Include02.xsd are XSD files referenced via import and include elements in MySchema.xsd.
