interface behaviour change: evaluate queries in the same static context => previous function declarations are available in later queries (requires function term cloning), test cases
how to calculate fibonacci numbers with higher order functions
fix warnings/hints (including actual bugs which luckily had no effect on the evaluation)
forgotten file
large scale refactoring: replace INamepace with string containing namespace url
  fix types: correctly parse types surrounded by parenthesis, remove too strict type checks from functions (which effectively broke all numeric and date/time functions on XML input), fix result type of functions when no type is given, add function(*) type annotation to schema
... fix for xxx-from-(date|time)
let XQTS harness compile again
raise correct error, when referencing missing/invalid functions
implement function coercion

omgwtf is that?
fix named references to type constructors
fix too strict type checking for user defined functions
fix function coercion of sequences
...
fix error code for function on fn:string, fn:data and atomization

(there we are now more correct than the standard itself, omg)
various stricter error checks for better XQTS results
