11903         * then the tag will be set to the one specified in the set call
11904         * which can be null. Also any of the settings setters that do not
11905         * take a tag as an argument effectively clears the tag.
11906         * </p><p>
11907         * For example, if you set settings A and B with tags T1 and T2 and
11908         * another app changes setting A (potentially to the same value), it
11909         * can assign to it a tag T3 (note that now the package that changed
11910         * the setting is not yours). Now if you reset your changes for T1 and
11911         * T2 only setting B will be reset and A not (as it was changed by
11912         * another package) but since A did not change you are in the desired
11913         * initial state. Now if the other app changes the value of A (assuming
