Sometimes implementors can leverage existing work, but not always -- for example, you can't just take Saxon's XPath implementation (which is one of the best) and plug it into Kweelt (one of the more promising XQuery-like implementations); the internal data structures are far too different. --Joe English jenglish@f...
