title: How do I add a field value to existing artifacts in WSO2 GREG?
body: <p>I would like to update the schema artifact type shipped with WSO2 GREG (Governance Registry) 4.5.3 with some additional fields. This is my new Artifact Source:</p>
  
  <pre><code>&lt;artifactType type="application/x-xsd+xml" fileExtension="xsd" shortName="schema" singularLabel="Schema" pluralLabel="Schemas" hasNamespace="true" iconSet="29"&gt;
  &lt;content href="../generic/schema_view_ajaxprocessor.jsp?hideStandardView=true"&gt;
      &lt;field &gt;
       &lt;name&gt;Gender&lt;/name&gt;
       &lt;values&gt;
        &lt;value&gt;male&lt;/value&gt;
        &lt;value&gt;female&lt;/value&gt;
       &lt;/values&gt;
  &lt;/field&gt;
  </code></pre>
  
  <p>
  </p>
  
  <p>It works when adding a new schema artifact, but when editing existing schema artifacts (existing before this update) I don't have the option to select a value for the field "Gender".</p>
  
  <p>Which options do I have to set the "Gender" values for my already imported schemas?</p>
