title: JAXB enumeration with numeric values
body: <p>I want to restrict input values like this</p>
  
  <pre><code>&lt;simpleType name="SomeCode"&gt;
    &lt;restriction base="string"&gt;
      &lt;enumeration value="036222B"/&gt;
      &lt;enumeration value="036111C"/&gt;
    &lt;/restriction&gt;
  &lt;/simpleType&gt;
  </code></pre>
  
  <p>But this does not generate an Enum. I suspect it is because the values start with numbers and this is not allowed for Enum values.</p>
  
  <p>Is there any solution or workaround?</p>
