XSLT 2.0 mapping in sap 7.5

Hi All

I have created an XSLT mapping and used a function for fetching current date which is available in XSLT 2.0

i followed the blog

https://blogs.sap.com/2014/10/14/how-to-import-and-use-xslt-20-mappings-in-sap-pipo/

But i am getting error " Error checking type of the expression 'funcall(current-dateTime, [])'."

How can i check if the SAXON parser is being used or not.

The same stylesheet works in NWDS with SAXON parser.

Regards
