  • Functions and variables support public and private annotations

  • Union types are allowed in function arguments

  • XML Schema 1.1 is supported

    • group by: assigns tuples in the input tuple stream to a group, returns a tuple for each group

    • tumbling window: destructing assignment of a sequence during iteration without intersection

    • sliding window: destructing assignment of a sequence during iteration with intersection

    • count clause: binds a variable to the position in each tuple in the tuple stream

    • allowing empty: facilitates outer joins as in SQL
