They cannot send me xml because they don't have technical knowledge. The y don't know anything how webservices work. I have the external xsd(I renamed them again in .xml) files but I think I tried once and the program said that the xsd was valitated correctly.
I am not an expert in xsd and xml and I don't have xmlspy to test it. I download the demo version but I don't know how to import external xsd and test or create a valid xml from that.
