Apply suggestions:

 * Forbid generics without a path (so "<p>" is forbidden).
 * Change `handleSingleArg` so that it takes `results_others`, `results_in_args` and `results_returned` as arguments instead of using the "global" variables.
 * Change `createQueryElement` so that it returns the newly created element instead of taking `elems` as argument.
 * Improve documentation
