We have a huge decision table having more than 1000 records. This decision table is delegated to business user and they kept on adding records. Now the business user wants the decision table to be case insensitive. Suppose the business user entered a value "No comments" in decision table they want to return that particular row result if the property value is "no Comments" ?
I think i see the trickiness of what you are saying. If it were me, I would probably move this data into a SQL table instead and delegate the data type (or a custom UI that automatically does case conversion on change) as directly delegated data tables (data types?) don't offer much control over validation.
