*
* <p>
* To see why, consider that generic elements are cloned before they are
* bound. However, they are not added to the original element's namespace.
* Thus, their fully qualified name (and that of the owned
* <code>TypeParameter</code>s) will be different. During binding, this would
* prevent recognizing two <code>TypeParameter</code>s as equal and therefore
* hinder binding. Thus, changing the qualified name to only include the
* parent solves this problem.
* </p>
*
* <p>
* Thus, this method returns a name that only includes the name of the owning
* {@link GenericElement} instead of the full namespace hierarchy. This should
* sufficiently identify any type parameter.
