>What version of the STL source is going to be in the standard?

You question indicates some confusion between the standard itself,
which will specify the interface to STL, and implementations of the
standard.  The standard itself won't contain any version of the STL source.
Rather, C++ implementations which aim to conform to the standard will
come with some version of the STL source code.

What makes you think that the compiler is supposed to conform to the
proposed standard?

The fact is that there are NO existing compilers which fully conform
to the draft proposed standard.  Remember, it is only a draft, and
it is still subject to change.  Even when the final version of the
standard is published, I think it will take compiler vendors a while to
produce conforming implementations (or at least almost-conforming --
all sufficiently complex programs contain bugs).

I think currently there may be no existing compilers which are
capable of compiling any version of STL which fully conforms to
the draft standard.  So compiler vendors ship with slightly
cut-down implementations of STL, such as the HP version, which do
not quite conform to the draft standard, but which are easier to compile.
Such versions avoid the use of more recently-introduced features such
as template template arguments, default template arguments, and so
forth.
