There are many problems in these two to point each one of them starting with the </schema> tag in the XSD which should be </xs:schema>
I would recommend you to check the standard XSD, XML files to see the structures they are using. Also, I guess there are templates of XSD and XML files which you can use to customize the BOD's.
At the moment, these two are far away from being usable. So, go ahead and check how the standards work and then start working on the custom.
Unless you try to do something beyond what you have already mastered, you will never grow!
