        \warning According to ISDA, "Actual/365" (without "Fixed") is

                 an alias for "Actual/Actual (ISDA)" (see

                 ActualActual.)  If Actual/365 is not explicitly

                 specified as fixed in an instrument specification,

                 you might want to double-check its meaning.
