Defining Element Content Models, Part 2

• Mixed Content    As in DTDs, mixed content is a choice model with a little extra:
  

  <elementRule role="paragraph">
     <mixed>
      <choice occurs="*">
        <ref label="name"/>
        <ref label="place"/>
      </choice>
    </mixed>
  </elementRule>

• Thoughts on data    The RELAX mailing list has also talked about the possibility of a similar syntax that allows unordered content but no mixed content to match recordset needs.
