  <h2><a name="typedef">Typedef</a></h2>
  <h3>Description</h3>
  <p>Adds a data type definition to the current project, such that this
  new type can be used in the current project. Two attributes are
  needed, the name that identifies this data type uniquely, and the full
  name of the class (including the packages) that implements this
  type.</p>
  <p>Typedef should be used to add your own types to the system. Data
  types are things like <a href="../using.html#path">paths</a> or <a
  href="../CoreTypes/fileset.html">filesets</a> that can be defined at
  the project level and referenced via their ID attribute.</p>
  <p>Custom data types usually need custom tasks to put them to good use.</p>
  <h3>Parameters</h3>
  <table border="1" cellpadding="2" cellspacing="0">
    <tr>
      <td valign="top"><b>Attribute</b></td>
      <td valign="top"><b>Description</b></td>
      <td align="center" valign="top"><b>Required</b></td>
    </tr>
    <tr>
      <td valign="top">name</td>
      <td valign="top">the name of the data type</td>
      <td valign="top" align="center">Yes</td>
    </tr>
    <tr>
      <td valign="top">classname</td>
      <td valign="top">the full class name implementing the data type</td>
      <td valign="top" align="center">Yes</td>
    </tr>
    <tr>
      <td valign="top">classpath</td> <td valign="top">the classpath to
        use when looking up <code>classname</code>.</td> <td
      align="center" valign="top">No</td>
    </tr>
  </table>
  <h3>Parameters specified as nested elements</h3>
  <h4>classpath</h4>
  <p><code>Typedef</code>'s <i>classpath</i> attribute is a 
  <a href="../using.html#path">PATH like structure</a> and can also be set
  via a nested <i>classpath</i> element.</p>
  <h3>Examples</h3>
  <pre>  &lt;typedef name=&quot;urlset&quot; classname=&quot;com.mydomain.URLSet&quot;/&gt;</pre>
  <p>makes a data type called <code>urlset</code> available to Ant. The
  class <code>com.mydomain.URLSet</code> implements this type.</p>
