how to validate my xml file with qm.xsd schema

Hello,

I have a requirement to validate my xml file with qm.xsd schema.

I usually validate with RAP (Rational app developer) as follows:

• Create schema file
• Create xml file using above Schema file. And can validate xml file with no problem.

But I could not validate my xml file against qm.xsd. Here is what I tried:

• I copied the qm.xsd schema file source code from - https://jazz.net/products/rational-quality-manager/api-doc-2.0/index.html
• Created schema file using above code. But it gave 356 erros. One of the errors is -             Attribute reference 'http://www.w3.org/1999/02/22-rdf-syntax-ns##resource' is unresolved qm.xsd

Can you please tell how to validate my xml file using qm.xsd? 

Thanks
