The problem is that top-level attribute declarations are not allowed to to have a use attribute.  Instead, your schema should look like:

<?xml version="1.0"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema">
   <element name="A">
      <complexType>
         <all>
            <element ref="B"/>
         </all>
         <attribute ref="TestAtt" use="required"/>
      </complexType>
   </element>
   <element name="B">
      <complexType>
         <attribute ref="TestAtt" use="required"/>
      </complexType>
   </element>
   <attribute name="TestAtt">
      <simpleType>
         <restriction base="positiveInteger">
            <enumeration value="1"/>
            <enumeration value="2"/>
         </restriction>
      </simpleType>
   </attribute>
</schema>
