                <ishideout> true</ishideout>
            </Castle>
    </Decoration>
</Product>

Also btw i have such a class hierarchy

P.S. i need to show in xsd a hierarchy of classes and that the base class is product class and all the childs will have a field name and price, so i'm not sure that it shows correctly in my schema :C and btw then im going to instantiate this classes

Because you have not Configure you root element properly so proper config Matters so 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">

<root>
  Paste your code here
</root>

so paste your code according suggested in this example. so paste your code in your root clauses whatever it is. and then error will be get shorted out.
