This is the command I'm running:

E:\Invoice\maindoc>xsd.exe /c UBL-Invoice-2.0.xsd UBL-CommonAggregat    eComponents-2.0.xsd UBL-CommonBasicComponents-2.0.xsd   UnqualifiedDataTypeSchemaModule-2.0.xsd UBL-CommonExtensionComponents-2.0.xsd UBL-QualifiedDatatypes-2.0.xsd

These are the errors I'm getting:

Solution

  • Most likely, there is another schema involved, and include schema, that has to be accounted for in the build.

    If the XSD is valid, then you should be able to pull all schemas involved into a project by using VS Project Add Existing Item, which will resolve or expose all problems with the XML schema.

    The one area that you can look it is the <namespace tag, which indicates what namespace the XML is in and is using.

    Make sure that you put in all xsd files, e.g.:

    xsd.exe /c sample1.xsd sample2.xsd sample2.xsd
