-/**
- * A base class for defining new tag handlers implementing Tag.
- *
- * <p> The TagSupport class is a utility class intended to be used as
- * the base class for new tag handlers. The TagSupport class
- * implements the Tag and IterationTag interfaces and adds additional
- * convenience methods including getter methods for the properties in
- * Tag. TagSupport has one static method that is included to
- * facilitate coordination among cooperating tags.
- *
- * <p> Many tag handlers will extend TagSupport and only redefine a
- * few methods.

- * This method uses the getParent method from the Tag

- * This method is used for coordination among cooperating tags.
- *
- * <p>
- * The current version of the specification only provides one formal
- * 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.
- * This addititional constraint can be exploited by a
- * specialized container that knows about that specific tag library,
- * as in the case of the JSP standard tag library.
- *
- * <p>
- * When a tag library author provides information on the
- * observable type of a tag handler, client programmatic code
- * should adhere to that constraint. Specifically, the Class
- * passed to findAncestorWithClass should be a subtype of the
- * observable type.
