Paragraph 24.3.2 [basic.string]/3 states:
The class template basic_string conforms to the requirements for a Sequence (23.1.1) and for a Reversible Container (23.1).
First of all, 26.2.3 [sequence.reqmts] is no longer "Sequence" but "Sequence container". Secondly, after the resent changes to containers (emplace, push_back, const_iterator parameters to insert and erase), basic_string is not even close to conform to the current requirements.
[ Bellevue: ]
- emplace, for example, may not make sense for strings. Is also likely suboptimal
- with concepts do we need to maintain string as sequence container?
- One approach might be to say something like: string is a sequence except it doesn't have these functions
- basic_string already has push_back
- const_iterator parameters to insert and erase should be added to basic_string
- this leaves emplace to handle -- we have the following options:
- option 1: add it to string even though it's optional
- option 2: make emplace optional to sequences (move from table 89 to 90)
- option 3: say string not sequence (the proposal),
- option 4: add an exception to basic string wording.
General consensus is to suggest option 2.

Move to NAD Editorial
Remove this sentence, in recognition of the fact that basic_string is not just a vector-light for literal types, but something quite different, a string abstraction in its own right.
