Extension of the reference manual "DB2 for i SQL Reference"

We have noticed that specifying a record format name when creating an SQL index always creates a derived index. In our case, access paths were therefore created twice. We were able to solve this problem by not specifying the record format name in future. Unfortunately, this behavior is not documented in any reference manual. It merely states: 

"With this support, an index can have an expression in place of a column name that can use built-in functions, or some other valid expression. Additionally, you can use the SQL CREATE INDEX statement to create a sparse index using a WHERE condition."

It would be good if, for example, a note could be found here that specifying the record format name also creates a derived index. 
We have not found any corresponding information elsewhere either.
