title: Custom DataTable/DataRow to XML serialization
body: <p>There are things that I dont like in DataTable.WriteXML() and .ReadXML(). These are:  </p>
  
  <ul>
  <li>Not possible to configure number of rows or columns to load/save.
  Need it when processing huge data amounts   </li>
  <li>Not even possible to get
  rid of the XML element that means dataset name (DocumentElement by
  default)</li>
  <li>Want to make custom processing on read/write nodes</li>
  </ul>
  
  <p>Is there any good serializer for DataRows and DataTables? I can write my own but it seems weird that they still don;t exist (i tried to find).<br>
  Thanks!</p>
