How can I import a vendor catalogue?

I have a XML file which I try to upload using the upload file button in the produrement and sourcing | common | catalogs | vendor catalogs | update | catalog file history.

When I do this  I receive an error:

Schema validation failed, This is an invalid xsi:type 'http://dax/vendorcatalog:Accessories'. and the import fails.

The XML schema looks like this:

<?

xml version="1.0" encoding="UTF-8"?>
<VendorCatalog xmlns="http://dax.com/vendorcatalog" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://dax.com/vendorcatalog C:/Users/agermarkp/Desktop/katalogtest.xsd" VendorName="Ford Operations" ProductClassification="Procurement Category">
<Product xsi:type="Accessories" ProductCode="020856615">
