/** specifies a SAX parser that uses integer values for known XML names
    (elements, attributes and attribute values). The parser also handles
    namespaces and allows to have individual contexts for each XML element.

    <p>Before parsing is possible you have to set your
    XFastDocumentHandler using setFastDocumentHandler().

    <p>Parsing starts with calling parseStream(). If the parser
    finds a valid XML file with the given InputSource, it calls
    XFastDocumentHandler::startDocument() first.

    <p>This parser generates either "fast" events that use integer token
    values for namespaces, elements and attributes or "unknown" events for
    elements that are unknown.

    <p>A namespace is unknown if the namespace URL was not registered with
    registerNamespace().

    <p>An element is unknown if no XFastTokenHandler is set
    or if the XFastTokenHandler does not return a valid
    identifier for the elements local name. An element is also unknown if
    the elements local name is known but it uses a namespace that is unknown.

    <p>Setting a XFastTokenHandler with setTokenHandler()
    is optional, but without a XFastTokenHandler you will only
    get unknown sax events. This can be useful if you are only interested
    in the namespace handling and/or the context feature.

    <p>For each element the parser sends a create child element event to the
    elements parent context by calling
    XFastContextHandler::createFastChildContext() for known
    elements or XFastContextHandler::createUnknownChildContext()
    for unknown elements.
    <br>The parent context for the root element is the XFastDocumentHandler
    itself.

    <p>If the parent context returns an empty reference, no further events for
    the element and all of its children are created.

    <p>If a valid context is returned this context gets a start event by a call to
    XFastContextHandler::startFastElement() for known elements or
    XFastContextHandler::startUnknownElement() for unknown elements.

    <p>After processing all its child elements the context gets an end event by a call to
    XFastContextHandler::endFastElement() for known elements or
    XFastContextHandler::endUnknownElement() for unknown elements.

    <p>It is valid to return one instance of XFastContextHandler more
    than once. It is even possible to only use the XFastDocumentHandler
    by always returning a reference to itself for each create child context event.

    <p>After the last element is processed the parser generates an end document
    event at the XFastDocumentHandler by calling
    XFastDocumentHandler::endDocument().
