That's a neat idea.
4XSLT does not support such a mode, nor do I know of any other processor
at all, regardless of language, that does. I think it could be extended
to support this by instrumenting all the XSLT element classes to
maintain a mapping from source node IDs to result sub-trees, and using
clever analysis to sync these in future based on this mapping.
This is not a feature I forsee in the near future for 4Suite, but it
sounds like it would be a neat project for someone else to take on.
