Further notes & tips

Here are some further notes & usefull tips:

• If some element or attribute is missing in the document, the corresponding method returns null.
• In some rare cases, the XSPFException or XSPFRuntimeException can be thrown. Think about that as like the IOException.
• After you set some element or collection, it's recomended to re-obtain all the corresponding view instances (the x() methods).
• Some more sample use cases can be found in the JUnit tests.
• The code is documented and quite well structured.
