This question could have been so much more than just a simple trick question. Instead of focusing on attribute or element centric mapping (which you did a bit with the answers and by specifying a non-existant bit flag), you made the question a whole lot less interesting.
The explanation doesn't even mention the different mappings and how they affect results.
Need an answer? No, you need a question
