Achieving Extensibility and Reuse for XSLT 2.0 Stylesheets

The appearance of the element() predicate and the ability to return source tree nodes from templates provides XSLT 2.0 with mechanisms to support extensibility and reuse in ways not available in XSLT 1.0. We present a significant example of these involving both vertical and horizontal changes, where a single stylesheet exploiting these features can be applied to incompatible but similar versions of a schema as well as to derived schemas created through using XSD's inheritance mechanisms.
