    <title>Model tags</title>
    <para>Model tags refer to data set by the output method of the model classes.
      They correspond to the HTML::Template.  The PageKit pre-processor simply
      replaces MODEL with TMPL before running the template through HTML::Template.

        This tag is very simple.  It is replaced by the corresponding value set
        in the Model by the output method.  You may also use ESCAPE="HTML" and ESCAPE="URL"
        to escape HTML, and URLs respectively.

      <para>
        This tag used for displaying a "table" of data.  The data is set from
	the model using the output method, and is a reference to an array
	of hash references.  Using the table analogy, the hash references are
	the rows, the keys of the 
	hash references are the column headers, the hash values are the data.
