title: enum with value starting with numbers in xsd
body: <p>My requirement is to have a element in the XSD to be restricted to some numbers</p>
  
  <pre><code>&lt;xs:element name="RequestType"&gt;
      &lt;xs:simpleType&gt;
      &lt;xs:restriction base="xs:string"&gt;
           &lt;xs:enumeration value="001"/&gt;               
           &lt;xs:enumeration value="002"/&gt;
           &lt;xs:enumeration value="003"/&gt;
      &lt;/xs:restriction&gt;
   &lt;/xs:simpleType&gt;
   &lt;/xs:element&gt; 
  </code></pre>
  
  <p>I tried using binding xml also but that is also not working</p>
  
  <pre><code>&lt;jxb:bindings node="//xs:simpleType[@name='RequestType']/xs:restriction/xs:enumeration[@value='001']"&gt;
     &lt;jxb:typesafeEnumMember name="Inquiry"/&gt;
  &lt;/jxb:bindings&gt;
  &lt;jxb:bindings node="//xs:simpleType[@name='RequestType']/xs:restriction/xs:enumeration[@value='002']"&gt;
        &lt;jxb:typesafeEnumMember name="Confirmation"/&gt;
  &lt;/jxb:bindings&gt;
  &lt;jxb:bindings node="//xs:simpleType[@name='RequestType']/xs:restriction/xs:enumeration[@value='003']"&gt;
       &lt;jxb:typesafeEnumMember name="Force Payment"/&gt;
  &lt;/jxb:bindings&gt;    
  </code></pre>
  
  <p>Can some one please help on this. </p>
