The last time we discussed what to do about standalone we punted and
decided to let people override printDeclaration(). I think the
complicating situation was that the standalone flag is partly an
attribute of the document and partly something to do with the outputter,
and we didn't like having it tied to either. I'm not saying we can't
add it, but it's non-obvious how best to add it.
