 /**
 26   
  * Parses a Tapestry Script, an XML file defined by one of the following public identifiers:
 27   
  * <ul>
 28   
  * <li><code>-//Primix Solutions//Tapestry Script 1.0//EN</code></li>
 29   
  * <li><code>-//Howard Ship//Tapestry Script 1.1//EN</code></li>
 30   
  * <li><code>-//Howard Lewis Ship//Tapestry Script 1.2//EN</code></li>.
 31   
  * <p>
 32   
  * The version 1.1, is largely backwards compatible to the old script, but adds a number of new
 33   
  * features (if, if-not, foreach and the use of property paths with insert).
 34   
  * <p>
 35   
  * Version 1.2 removes the &lt;insert&gt; element, using an Ant-like syntax (
 36   
  * <code>${<i>expression</i>}</code>). It also replaces the attribute name
 37   
  * <code>property-path</code> with <code>expression</code> (because OGNL is used).
 38   
  * <p>
 39   
  * A Tapestry Script is used, in association with the {@link org.apache.tapestry.html.Body}and/or
 40   
  * {@link org.apache.tapestry.html.Script}components, to generate JavaScript for use with a
 41   
  * Tapestry component. Two seperate pieces of JavaScript can be generated. The body section
 42   
  * (associated with the <code>body</code> element of the XML document) is typically used to define
 43   
  * JavaScript functions (most often, event handlers). The initialization section (associated with
 44   
  * the <code>initialization</code> element of the XML document) is used to add JavaScript that
 45   
  * will be evaluated when the page finishes loading (i.e., from the HTML &lt;body&gt; element's
 46   
  * onLoad event handler).
