The Custom Validation Definitions Pane
The Custom Validation Definitions Pane shows a list of the custom validation definitions that you have added and their attributes which you can edit as needed
Editor Text
Editor text is the text that appears in the Currently Applied Validation pane next to the checkbox to select or deselect the validation type.
