-/**
- * The interface of a classic tag handler that does not want to manipulate
- * its body. The Tag interface defines the basic protocol between a Tag
- * handler and JSP page implementation class. It defines the life cycle
- * and the methods to be invoked at start and end tag.
- *
- * <p><B>Properties</B></p>
- *
- * <p>The Tag interface specifies the setter and getter methods for the core
- * pageContext and parent properties.</p>
- *
- * <p>The JSP page implementation object invokes setPageContext and
- * setParent, in that order, before invoking doStartTag() or doEndTag().</p>
- *
- * <p><B>Methods</B></p>
- *
- * <p>There are two main actions: doStartTag and doEndTag. Once all
- * appropriate properties have been initialized, the doStartTag and
- * doEndTag methods can be invoked on the tag handler. Between these
- * invocations, the tag handler is assumed to hold a state that must
- * be preserved. After the doEndTag invocation, the tag handler is
- * available for further invocations (and it is expected to have
- * retained its properties).</p>
- *
- * <p><B>Lifecycle</B></p>
- *
- * <p>Lifecycle details are described by the transition diagram below,
- * with the following comments:
- * <ul>
- * <li> [1] This transition is intended to be for releasing long-term data.
- * no guarantees are assumed on whether any properties have been retained
- * or not.
- * <li> [2] This transition happens if and only if the tag ends normally
- * without raising an exception
- * <li> [3] Some setters may be called again before a tag handler is
- * reused. For instance, <code>setParent()</code> is called if it's
- * reused within the same page but at a different level,
- * <code>setPageContext()</code> is called if it's used in another page,
- * and attribute setters are called if the values differ or are expressed
- * as request-time attribute values.
- * <li> Check the TryCatchFinally interface for additional details related
- * to exception handling and resource management.
- * </ul></p>
- *
- * <IMG src="doc-files/TagProtocol.gif"
- * alt="Lifecycle Details Transition Diagram for Tag"/>
- *
- * <p>Once all invocations on the tag handler
- * are completed, the release method is invoked on it. Once a release
- * method is invoked <em>all</em> properties, including parent and
- * pageContext, are assumed to have been reset to an unspecified value.
- * The page compiler guarantees that release() will be invoked on the Tag
- * handler before the handler is released to the GC.</p>
- *
- * <p><B>Empty and Non-Empty Action</B></p>
- * <p>If the TagLibraryDescriptor file indicates that the action must
- * always have an empty action, by an <body-content> entry of "empty",
- * then the doStartTag() method must return SKIP_BODY.</p>
- *
- * <p>Otherwise, the doStartTag() method may return SKIP_BODY or
- * EVAL_BODY_INCLUDE.</p>
- *
- * <p>If SKIP_BODY is returned the body, if present, is not evaluated.</p>
- *
- * <p>If EVAL_BODY_INCLUDE is returned, the body is evaluated and
- * "passed through" to the current out.</p>

- * way of indicating the observable type of a tag handler: its
- * tag handler implementation class, described in the tag-class
- * subelement of the tag element. This is extended in an
- * informal manner by allowing the tag library author to
- * indicate in the description subelement an observable type.
- * The type should be a subtype of the tag handler implementation
- * class or void.

- * specialized container that knows about that specific tag library,
