I am trying to genrate apex code from WSDL.  and I am getting error message:"Failed to parse wsdl" The error is at following 3 ines:
            <xs:attribute name="FactoryType" type="xs:QName"/>
            <xs:attribute name="Id" type="xs:ID"/>
            <xs:attribute name="Ref" type="xs:IDREF"/>


So I commented it and saleforce is able to parse. Now, when I try to generate code it fails:

Unsupported schema type: {http://www.w3.org/2001/XMLSchema}unsignedByte

Please help me. I am totally lost.
The WSDL is as follows:
