Quoting the standard:

        3.358 Standard Error

        An output stream usually intended to be used for diagnostic messages.

        [...]

        3.360 Standard Output

        An output stream usually intended to be used for primary data output.


Of course, this definition is meant for typical unix command line
tools, where you want to pipe the output of one program as input
into another program and still see "diagnostic messages" from the
first program. Lilypond is a little bit different.
