o_xml generation by 22-30% depending upon the model. This is done

integers. I've attached a small script you can use to time the
to_xml before
and after the patch.
3) Allows the :include option to be arbitrary deep, previously,
only one level
of :include worked.
4) Binary columns are Base64 encoded and have an encoding="base64"
attribute
added to it. It turns out that it is 80 times faster to do builder <<
Base64.encode(value) then builder.tag!(tag, value).
Outstanding issues are
1) The XML output is not at nice looking with the optimization of
using
builder.tag!(tag) do
builder << value.to_s
end
The new Builder "escape all" approach is a bit absurd, especially
considering it's doing packs/unpacks to secure all Unicode values
outside of ASCII. I tried to devise a patch to that but the stuff is
buried too deep and Jim didn't seem keen on the idea.
