This seems very complicated and error prone to me.

One technical problem that it does not address is that it
assumes the document sequence (e.g. replacement) can be produced

In all of my uses of my 'subtree' step in smallx, I take the
element that matched and use it to *produce* the replacement.  As
such, the above component, as described, would not work.

Also, this kind of component is practically impossible to stream.
