    "A CD .xml parsing example. The parser raises a UserNotification

     whenever it parses a CD, it raises a UserNotification. The notification

     is then handled and printed. Demonstrates:

      - proxy creation

      - exception handling

    cd.xml may look like:

    <?xml version='1.0' encoding='ISO-8859-1'?>

    <catalog>

        <cd>

            <title>Empire Burlesque</title>

            <artist>Bob Dylan</artist>

            <country>USA</country>

            <company>Columbia</company>
