>From an implementation point of view, it is important that you use exactly
the methods already present in the exporter. However, there are
possibilities, for example, for "caching" spheres in the exporter and then
expressing them at the end. This is conceivable. There is a "finalize"
method that is run that the exporter can use to do whatever it wants. It
would involve a Hashtable. I'd have to take a look at how flexible the
macros are, but I don't think there would be a huge savings just be caching
spheres.
