+=== API Changes ===
+
+The following function will be added:
+
+
+{{{
+FDO_API FdoCompareType FdoDataValue::Compare( FdoDataValue* other );
+}}}
+
+where the input parameter ''other'' is the other value to compare against the current value.
+
+The return values can be one of the following:
+
+''!FdoCompareType_Equal'': this and the other value are equal or both null[[br]]
+''!FdoCompareType_Greater'': this value is greater than the other value[[br]]
+''!FdoCompareType_Less'': this value is less than the other value[[br]]
+''!FdoCompareType_Undefined'': these two values are different but cannot be compared. 
+
+Cases where !FdoCompareType_Undefined happens are:
+
+• their types are incompatible[[br]]
+• one value is null and the other value is not[[br]]
+• both values are Boolean and one is true and the other is false[[br]]
+
+The following enumeration will be added:
+
+
+{{{
+enum FdoCompareType
+{
+    FdoCompareType_Undefined,
+    FdoCompareType_Less,
+    FdoCompareType_Greater,
+    FdoCompareType_Equal
+};
+}}}
