The error message is a bit obscure and doesn't really explain what the
problem is. Your problem is that you cannot place occurence constraints
on global element and attribute definitions. In your schema you have the
global element contact with a maxOccurs attribute which is not legal so
remove the occurence constraint and you should be ok. If you want to
have up to 99 contact elements in the instance document then you have to
wrap them in a single root element like for example:

<xsd:element name="contacts">
   <xsd:complexType>
      <xsd:sequence>
         <xsd:element name="contact" type="means" maxOccurs="99" />
      </xsd:sequence>
   </xsd:complexType>
</xsd:element>

Since you're using a targetNamespace you also need to add a namespace
declaration for this namespace. This can for example be a default
namespace declaration on the <xsd:schema> element like this:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.xmlforia.org"
xmlns="http://www.xmlforia.org">

Cheers,
