(this is basically reopening the first part of issue 2006, as discussed in the thread starting at c++std-lib-30698 )Section 21.2.6 [associative.reqmts] In Table 102, several uses of T (which means mapped_type here) should be value_type instead. This is almost editorial. For instance:
Requires: T shall be EmplaceConstructible into X from args.Effects: Inserts a T object t constructed with std::forward<Args>(args)... if and only if there is no element in the container with key equivalent to the key of t. The bool component of the returned pair is true if and only if the insertion takes place, and the iterator component of the pair points to the element with key equivalent to the key of t.

Not even an exhaustive list of problem locations. No reason to doubt issue.
Pablo agrees to provide wording.

[2014-02-15 post-Issaquah session : move to Resolved]
AJM to replace this note with a 'Resolved By...' after tracking down the exact sequence of events, but clearly resolved in C++14 DIS.
In both section 21.2.6 [associative.reqmts] Table 102 and 21.2.7 [unord.req], Table 103, make the following text replacements:
|Original text, in FDIS||Replacement text|
|T is CopyInsertable into X and CopyAssignable.||value_type is CopyInsertable into X, key_type is CopyAssignable, and mapped_type is CopyAssignable (for containers having a mapped_type)|
|T is CopyInsertable||value_type is CopyInsertable|
|T shall be CopyInsertable||value_type shall be CopyInsertable|
|T shall be MoveInsertable||value_type shall be MoveInsertable|
|T shall be EmplaceConstructible||value_type shall be EmplaceConstructible|
|T object||value_type object|
