The inherited method called when a tag is being closed.
This method calls the user-implemented methods myCharacters with the previously collected and converted characters.
Then, myEndElement is called, supplying it the qname converted to its enum- and string-representations.

The method parses the supplied XMLCh*-qname using the internal name/enum-map to obtain the enum representation of the attribute name.
Then, "myStartElement" is called supplying the enumeration value, the string-representation of the name and the attributes.
