Release 3.0: more efficient, easier to implement
Version 3 is a modular rewrite that is much easier to maintain, debug, and implement.
- more efficient: multiple XSD documents are loaded less often;
- easier to implement (for all use cases the same files can be used);
- platform-independent: tested and supported with XSLT 1-3 in all common implementations (including browser);
- removed support for XHTML: there are virtually no use cases for it, and it is one more version to maintain.
