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.

<div class="block">Find the instance of a given class type that is closest to a given

This method uses the getParent method from the Tag
interface.
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 additional 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.</div>
