[[limitations_for_window_functions]]
== Limitations for Window Functions
-These limitations apply to all window functions.
+Trafodion supports many ANSI compliant OLAP window functions. These
functions include AVG, COUNT, DENSE_RANK, MAX, MIN, RANK, ROW_NUMBER, STDDEV,
SUM, and VARIANCE. However, Trafodion imposes certain limitations on all window
functions.

This is correct, since it says "include". But since you are already
editing, would you want to include LEAD, LAG, FIRST_VALUE, LAST_VALUE?
