  +    <q>Does Xerces DOM implement java.io.Serializable?</q>
  +    <a>
  +      <p>Yes. Xerces DOM can be serialized using Java object serialization.
  +         It is recommended that a DOM be serialized as 
  +         <link anchor='dom-xml-serialization'>XML</link> where possible
  +         instead of using object serialization.
  +      </p>
  +      <p>By choosing object serialization you sacrifice interoperability 
  +         between parsers and we do not guarantee interoperability 
  +         between versions of Xerces. It should be used with caution.
  +      </p>
  +      <p>Some rough measurements have shown that XML serialization performs
  +         better than Java object serialization and that XML instance documents 
  +         require less storage space than object serialized DOMs.
