The Saxon XSLT processor implements the XSLT 1.0 and XPath 1.0 Recommendations from the World Wide Web Consortium, found at http://www.w3.org/TR/xslt and http://www.w3.org/TR/xpath, which are referred to here collectively as "XSLT"
Saxon remains 100% conformant to the mandatory requirements of these recommendations, except in those cases where incompatibilities have been introduced in the XSLT 2.0 and XPath 2.0 working drafts.
For maximum conformance to XSLT 1.0 and XPath 1.0, the recommended product is Saxon 6.5.3.
