The SAX <code>startElement</code> method recognizes elements
from the plain catalog format and instantiates CatalogEntry
objects for them.

@param namespaceURI The namespace name of the element.
@param localName The local name of the element.
@param qName The QName of the element.
@param atts The list of attributes on the element.
