XML tools for Java. Independent on any specific processor. The main focus of this is to assist with writing EXPath implementations in Java.

For now, it is mainly a data model for abstracting XML nodes in Java. It has been retro-fitted from other existing projects for extension functions in Java (for Saxon, eXist-db and QuizX). The model is still ad-hoc now, and its design is not stable (nor good as far as I am concerned). The goal is to refactor it in successive iterations.
