/* A child element without own child elements may contain a single space
character, for example:
<div>
<font><i>abc</i></font>
<font> </font>
<font><b>def</b></font>
</div>
represents the italic text 'abc', an unformatted space character, and
the bold text 'def'. Unfortunately, the XML parser skips the space
character without issuing a 'characters' event. The class member
'mnInitialPortions' contains the number of text portions existing when
this context has been constructed. If no text has been added in the
meantime, the space character has to be added manually.
