You want complexType with simpleContent in order to do that. Use this:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:simpleType name="st">
 <xs:restriction base="xs:string">
  <xs:enumeration value="int8"/>
  <xs:enumeration value="int16"/>
 </xs:restriction>
</xs:simpleType>

<xs:element name="DataType">
 <xs:complexType>
  <xs:simpleContent>
  <xs:extension base="xs:string">
   <xs:attribute name="IsArray" type="xs:string"/>
  </xs:extension>
  </xs:simpleContent>
 </xs:complexType>
</xs:element>
</xs:schema>
