There appears to be no requirements on the InputIterators used in sequences in 23.1.1 in terms of their value_type, and the requirements in 23.1.2 appear to be overly strict (requires InputIterator::value_type be the same type as the container's value_type).
Change 23.1.1 p3:
In Tables 82 and 83, X denotes a sequence class, a denotes a value of X, i and j denote iterators satisfying input iterator requirements , [i, j) denotes a valid range, n denotes a value of X::size_type, p denotes a valid iterator to a, q denotes a valid dereferenceable iterator to a, [q1, q2) denotes a valid range in a, and t denotes a value of X::value_type.
Change 23.1.2 p7:
In Table 84, X is an associative container class, a is a value of X, a_uniq is a value of X when X supports unique keys, and a_eq is a value of X when X supports multiple keys, i and j satisfy input iterator requirements and refer to elements
ofvalue_type, [i, j) is a valid range, p is a valid iterator to a, q is a valid dereferenceable iterator to a, [q1, q2) is a valid range in a, t is a value of X::value_type, k is a value of X::key_type and c is a value of type X::key_compare.
Concepts will probably come in and rewrite this section anyway. But just in case it is easy to fix this up as a safety net and as a clear statement of intent.
