/**
 *	<p>Some of the {@link org.ditchnet.jsp.util.JspResponseWriter} class' 
 *	public instance methods write markup (XML, specifically) to the response
 *	stream. The <code>Xml</code> interface, it's static inner interfaces
 *	<code>Tag</code> and <code>Attr</code> enforce type-safety and decrease the
 *	likelyhood of malformed XML (which is not truely XML anyway) being 
 *	generated by the JspResponseWriter class.</p>
 *	<p>For example the <code>JspResponseWriter</code>'s <code>startElement()</code>
 *	method accepts one parameter of type <code>Xml.Tag</code> instead of just a
 *	<code>String</code>. Again, this ensures type safety, but more importantly,
 *	allows a fixed set of markup elements to be sent to the response stream
 *	making XML well-formedness errors much less likely.</p>
 *	<p>This class is purely a utilitly class, and may not be instaciated 
 *	by client code (private constructor).</p>
 *	<p>Note that the {@link org.ditchnet.xml.Xml.Tag} class implements
 *	the Type-Safe Enum Pattern as described by Joshua Bloch in <em>Effective
 *	Java</em>.</p>
 *	<p>Subclasses of this class should represent a specific XML vocabulary
 *	or application. For example, the {@link org.ditchnet.xml.Xhtml}
 *	class represents the XHTML vocabulary.</p>
