  @enDesc:
    Note that the <Class::ManakaiXMLParser> reports any XML errors
    (syntax errors and / or well-formedness constraint errors)
    via the <IF::DOMCore:error-handler> registered to
    the <A::DOMLS:LSParser.domConfig> object.  Each error has
    its <A::DOMCore:DOMError.severity>, either <C::DOMCore:SEVERITY_ERROR>
    or <C::DOMCore:SEVERITY_FATAL_ERROR>.  However, their semantics
    are slight different from the ones of <QUOTE::error> and
    <QUOTE::fatal error> in XML; in this implemenetation, 
    <C::DOMCore:SEVERITY_ERROR> implies that the parsing process
    can effectively be continued to detect more errors while
    <C::DOMCore:SEVERITY_FATAL_ERROR> implies that the error
    is serious so that the result document tree and any errors
    might be far from the ones obtained when the error would not
    be found.
