No, not yet. :)

I see two possibilities: add a "prependPI(pi)" method to ElementTree, or add a
method "addToTree(tree)" method to ProcessingInstruction. We might then also
need a way to get rid of them again - although, well, you could always move
them to a different tree, which would obviously remove them from the current one.

Ok, so any preferences?
