User defined function in SQL Expression

I am trying to create a function which will be used in the WHERE clause and which will use dynamic sql. I know that when calling a function from an SQL Expression the function must have
PRAGMA RESTRICT_REFERENCES(function_name, WNDS)

My problem is I can not state the pragma WNDS as DBMS_SQL parse and execute do not have these restrictions.
The function I am trying to create will only ever SELECT never INSERT, UPDATE or DELETE data.

Can anyone help, any help will be greatly appreciated.

Thanks in advance
