RE: XQuery Implementations

Indeed the Fraunhofer IPSI-XQ Engine implements
the static type reasoning of XQuery in Java. Its
development parallels Galax the AT&T/Bell-Labs/Avaya Labs
implementation, which is implemented in OCaml like XDuce.

Going open source or source-forge is one of the exploitation/transfer
options being discussed, but there has been no final decision.

Best regards,

Peter
