They are not empty, they correspond to the whitespace between <UseCases>
and <UseCase>.

If you want to ignore it, you need to create a subclass of DOM_SAXDriver
and override the #ignorableWhitespace: method.  The overridden method
can simply do nothing.  Then to use your driver call this before
starting the parse:

    parser saxDriver: NoWhitespaceSAXDriver new
