For XSD and XFactTable, we can try using xs:restriction in XSD. Something as 
below:
  <xs:attribute name="weight">
    <xs:simpleType>
      <xs:restriction base="xs:double">
        <xs:minExclusive value="0"></xs:minExclusive>
      </xs:restriction>
    </xs:simpleType>
  </xs:attribute>
  
  and then using <xs:attribute ref="weight" use="required"/> in 
XDimensionTablea nd XFactTable defintion in XSD.
  
  
For test case, one integration test case which makes sure that FactTable 
creation gracefully fails when a fact is created with missing weight and one 
unit test case which ensures that CubeFactTable instance creation throws 
IllegalArgumentException when it is created with weight <= 0 shall give us 
sufficient coverage.
