DBMS_XSLPROCESSOR.SETPARAM problem

Question

When I try to pass values of global parameters of stylesheet with DBMS_XSLPROCESSOR.SETPARAM I get "ORA-31020: The operation is not allowed, Reason: Invalid XSL Parameter or its Value". Can someone provide me with working example, please?
Database version Oracle XE 11g 11.2.0.2.0
