1. make work with different SAC parsers

2. indirect the creation of XML so that different output formats could be used
- at present the Document Handler calls XMLWriter directly, if output were indirected 
then the same framework could be used to create e.g. a JSON [1] serialization, 
alternatively a writer could be created to do that

3. introduce a pretty printed option

4. think about whether the value element needs to be made more elaborate 
e.g. introduce specific property and corresponding value structures 

5. Think about selectors as XPATHs
