<p>The &1 is one of several TransformationBeans&#153;
 that are considered composite components.
A composite component allows a developer to design custom components
 that are made up of a combination of other components,
 such as TextEntry, ListBox, and Label TransformationBeans&#153;.
The visual layout of a composite component can be easily controlled
 through a template.
For more information on composite TransformationBeans&#153;,
