* Support for functions (views) and modules.
* Support for computed constructors.
* Preliminary support of conditional expressions in the return clause.
* Enhanced support of standard XQuery serialization allowing (as much as possible) the user to get uniform and conformant output.

XQuark Fusion can also directly access XML documents.
