Requirements on iterators swapping allegiance would disallow the small-string optimization.
[ Resolved in Rapperswil by paper N3108. ]
Add an exclusion for basic_string to the sentence beginning “Every iterator referring to an element...”. Add a sentence to 188.8.131.52/2 saying that iterators and references to string elements remain valid, but it is not specified whether they refer to the same string or the other string.
