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.

Many tag handlers will extend TagSupport and only redefine a few methods.</div>

<div class="block">Find the instance of a given class type that is closest to a given instance. This method uses the getParent

<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.</div>
