Table 37, in 24.2.1 [char.traits.require], descibes char_traits::assign as:
X::assign(c,d) assigns c = d.
And para 1 says:
[...] c and d denote values of type CharT [...]
Naturally, if c and d are values, then the assignment is (effectively) meaningless. It's clearly intended that (in the case of assign, at least), 'c' is intended to be a reference type.
I did a quick survey of the four implementations I happened to have lying around, and sure enough they all have signatures:
assign( charT&, const charT& );
(or the equivalent). It's also described this way in Nico's book. (Not to mention the synopses of char_traits<char> in 184.108.40.206 and char_traits<wchar_t> in 220.127.116.11...)
Add the following to 21.1.1 para 1:
r denotes an lvalue of CharT
and change the description of assign in the table to:
X::assign(r,d) assigns r = d
