I understand that I can now get the content of an extracted file (for a given schedule) in a single call: 
../Extractions/Schedules('12345')/LastExtraction/$value 
../Extractions/Schedules('12345')/LastExtraction/FullFile/$value 
../Extractions/Schedules('12345')/LastExtraction/NotesFile/$value 
1. What is the difference between the "/LastExtraction/$value" and "/LastExtraction/FullFile/$value" calls? 
2. Are these calls treated as synchronous? 
3. Is there any documentation with examples available?
