title: xsd2code element namespace prefix issue
body: <p>I am using the xsd2code VS plug-in to create some data classes from a couple of xsd files and I'm having an issue where the namespace prefix for elements in the XSD do not appear in the generated XML files. </p>
  
  <p>XSD:</p>
  
  <pre><code>&lt;xsd:complexType name="ProductMasterItemType"&gt;
    &lt;xsd:sequence&gt;
      &lt;xsd:element ref="cmn:PrimaryItemCode"/&gt;
      &lt;xsd:element ref="cmn:NewPrimaryItemCode" minOccurs="0"/&gt;
      &lt;xsd:element ref="cmn:ProductGroupCode"/&gt;
      &lt;xsd:element ref="cmn:ProductStatus"/&gt;
      &lt;xsd:element ref="cmn:EffectiveDate" minOccurs="0"/&gt;
      &lt;xsd:element ref="cmn:RecordStatus"/&gt;
      &lt;xsd:element name="AlternateItemCodes"
                   type="cmn:AlternateItemCodeListType" 
                   minOccurs="0"/&gt;
      &lt;xsd:element name="TargetMarketList" 
                   type="mdx:TargetMarketListType" 
                   minOccurs="0"/&gt;
      &lt;xsd:element name="ItemInfoList" 
                   type="mdx:ItemInfoListType"/&gt;
      &lt;xsd:element name="PackagingInfoList" 
                   type="mdx:PackagingInfoListType" 
                   minOccurs="0"/&gt;
    &lt;/xsd:sequence&gt;
  &lt;/xsd:complexType&gt;

  <p>The generated XML doesn't have the 'cmn' namespace prefix for the elements. Did I generate the classes incorrectly when I ran the plug-in? Is this something I need to change in the plug-ins source code?</p>
  
  <p>I don't have a lot of experience working with XML so I apologize if this isn't enough information. If I'm missing something you'd need to know to help answer let me know! Thanks in advance :)</p>
