Hello,

are there already any plans for implementing the XQuery 3.0 feature "window clause in FLWOR expressions"?

It seems to me so interesting as it allows the creation and evaluation of "self describing item streams", that is, streams of XDM items with interspersed control items which define and annotate sub units (windows) of the stream total, thus effectively translate the stream of items into a stream of larger units, in analogy to XML tags which translate a stream of characters into a stream of information items...

Thank you,

Hans-Juergen
