Thanks Pavel and Alan. 

I updated the return value to be separated by '@'. I also updated the specification wording so that users will be cautious when using this value as @ecki suggested. I used phrasing similar to the second example in Effective Java Item 12. I expect the 'subject to change' will ensure people do not depend on it.
