Am I missing a point here? When asking for an element that does not exist, what way to communicate this problem is chosen? As far as I can see, all elements are generated if not found.
This might be one use case when I want to edit documents, but the largest portion of work might also be to ask for an element pointed to and get a clear "not found" result in form of null or exceptions - but I cannot find this in the code.
Will this be added?
