 * <!-- begin-user-doc -->
 * A representation of the model object '<em><b>Function</b></em>'.

 *
 * <!-- begin-model-doc -->
 * @since J2EE1.4
 * The function element is used to provide information on each
 * function in the tag library that is to be exposed to the EL.
 * 
 * The function element may have several subelements defining:
 * 
 * description         Optional tag-specific information
 * 
 * display-name        A short name that is intended to be
 *                     displayed by tools
 * 
 * icon                Optional icon element that can be used
 *                     by tools
 * 
 * name                A unique name for this function
 * 
 * function-class      Provides the name of the Java class that
 *                     implements the function
 * 
 * function-signature  Provides the signature, as in the Java
 *                     Language Specification, of the Java
 *                     method that is to be used to implement
 *                     the function.
 * 
 * example             Optional informal description of an
 *                     example of a use of this function
 * <!-- end-model-doc -->
