No, you've got it completely the wrong way around! Saxon uses a different data structure for RTFs from its normal tree model, and it's this different data structure that has a bug in it! But you can't prove anything from bugs, especially performance bugs. They can happen anywhere at any time. This one happened because RTFs are usually small, which meant that a scalability problem in this area didn't show up in all the standard performance tests; the same bug in the tree model used for input documents would have shown up very quickly.
