My implementation of CodeSharing is too slow. I've built a brand-new eXist and put MoEML into it, and I'm working with it locally to test improvements.

After much pain and suffering, I eventually discovered that doing the transformation inside the XQuery with transform:transform is WAY faster than passing it on to a view in the controller. It's still nowhere near as fast as I'd like, but it's better; I now have a problem to solve related to the relative location of the stylesheet, but I'll get to that.
