        <p>
          The following is a list of items that need to be completed in
          Jelly.  Contributions are welcome!.
        </p>
        <ul>
          <li>autogenerate tag library documentation, in a kinda javadoc style, showing
all tag libraries, 
  			their tags and descriptions of their tags</li>
          <li>Patch TagLibrary to alias all &lt;mixedCase&gt; tags to &lt;mixed-case&gt;
 tags</li>
  		<li>Add tags &lt;copy&gt; &lt;copyOf&gt; &lt;element&gt;
&lt;attribute&gt; to JSL </li>
  		<li>Add JSL test cases to test for ordering of patterns and that the correct output
comes out.</li>
  		<li>Rename the DynaTag interface to be DynamicAttributes along with JSP1.3, 
  			also add a namespace URI parameter
  		</li>
  		<li>Add JUnit tags along these lines...
  <pre>&lt;junit:assert test="${foo == 22}"&gt;some description&lt;/junit:assert&gt;
  &lt;junit:assertEquals value="${foo}" expected="${22}"&gt;some description&lt;/junit:assert&gt;
  </pre>
  		</li>
  		<li>Add support for namespace URI use inside XPath expressions.</li>
  		<li>When defining new tags using &lt;define:tag&gt;, we should allow attributes
to be named,<br/>
  			specified as required, specify the optional conditions and so forth for validating instances.<br/>

  			I guess this could just be normal script though.
  		</li>
  		<li>The org.apache.commons.jelly.impl package doesn't have a great name - <br/>
  			Can we think of a better one? <br/>
  			Also some of the classes in this package could maybe do with a rename? <br/>
  			ScriptBlock for example - should we just call it a Block or maybe a CompositeScript?
  		</li>
  		<li>Add EmptyScript to allow tags optimise if their body is empty.</li>
  		<li>Add whitespace trimming support. <br/>
  			Allow a taglib to decide which tags 'trim' and which don't so that<br/>
  			unnecessary whitespace can be removed at compile time.
  		</li>
  		<li>Add parent Context and support for other scopes such as session, <br/>
  			request, cookie, initParam, param etc.<br/>
  			Maybe add a Scope class for variable names which can contain a scope name <br/>
  			and variable name. Then things like  cookie:foo or initParam:bar can be parsed <br/>
  			at compile time into an object.<br/>
  		</li>
  		<li>Add getResource() and getResourceAsStream() methods from ServletContext to <br/>
  			Context to allow  included files to be loaded etc.
  		</li>
  		<li>Add an adapter to run JSP tag libraries inside Jelly when Jelly is used in a

  			Servlet / JSP environment?
  		</li>
  		<li>Document much more!</li>
  		<li>Provide an alternative non-XML parser such that Jelly scripts do not<br/>
  			need to be XML. This could allow Velocity-style concise notation <br/>
  			for common Jelly tags.
  		</li>
  		<li>Provide easy compile time tag transformations. Here are some possible use cases
  <pre>
  &lt;magic:form&gt;
  	&lt;form&gt;
  		  &lt;input name="foo"&gt;
  		  &lt;input name="bar"&gt;
  	&lt;/form&gt;
  &lt;/magic:form&gt;
  </pre>
  			Then at 'parse/compile' time the &lt;magic:form&gt; could transform its fragment
  			of real HTML into
  <pre>
  &lt;form&gt;
    &lt;input name="foo" &lt;j:expr value="${foo}"&gt;
    &lt;input name="bar" &lt;j:expr value="${bar}"&gt;
  &lt;/form&gt;
  </pre>
  			i.e. tags can just be a simple transformation mechansim that can add some<br/>
  			common programatical guff to scripts. <br/>
  							Or <br/>
  			We could do SOAP scripting...<br/>
  <pre>
  &lt;babelfish:translate from="EN" to="FR"&gt;
  	hello Geir
  &lt;/babelfish:translate&gt;
  </pre>
  			The &lt;babelfish:translate&gt; tag could really just be a small 'macro'<br/>
  			autogenerated from a SOAP WSDL file that expands in place to the full SOAP<br/>
  			equivalent of<br/>
  <pre>
  &lt;io:soap url=http://babelfish.altavista.com/soap 
              SOAPAction="urn:babelfish"&gt;
     &lt;io:body&gt;
  	 &lt;SOAP-ENV:Envelope
  			xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
  			SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"&gt;
  	    &lt;SOAP-ENV:Body&gt;
  		 &lt;babelfish:translate xmlns:babelfish="bablefish.altavista.com" from="EN" to="FR"&gt;
  					hello Geir
  		 &lt;/babelfish:translate&gt;
  		&lt;/SOAP-ENV:Body&gt;
  	 &lt;/SOAP-ENV:Envelope&gt;
     &lt;/io:body&gt;
  &lt;/io:soap&gt;
  </pre>
  		  So its more of a traditional macro - though could be implemented using XML<br/>
  		  technology for the transformation (e.g .it could use SAX, XSLT, XPath or<br/>
  		  DVSL to transform itself and its body).
  		</li>
  
  	  </ul>
      </section>
      <section name="Ponder about"> 
        <p>
          The following is a list of things that might be good to add to Jelly, maybe after
more thought.
        </p>
        <ul>
          <li>
  			maybe consider a tag which will switch the default EL to XPath; then XPath and EL can
be peers. Then ${foo}
  			can be used as an XPath expression anywhere
  		</li>
  		<li>
  			Consider using &lt;jsl:stylesheet var="foo"&gt; then reusing the stylesheet later
via 
  <pre>
  &lt;style stylesheet="${foo}"&gt;
  	xml goes there...
  &lt;/style&gt;</pre>
  		</li>
  	  </ul>
      </section>
    </body>
  </document>
