   The decision to make it open-source has been made, thanks to RefinedData Inc. 
for the contribution. Now I need to talk to Michael Key, if he would like to 
take it on board, since it is Saxon based solution.

   Adapter allows to mix JCR XPath, direct node retrieval by UUID and Saxon 
XPath 2.0 and XQuery 1.0 to achieve optimal performance. We are using it in 
production for reporting.

   I will keep you posted.
