Required Text. The displayed name for the column. Maximum length is 255 characters.
The value of this attribute is used as a column heading when the field is displayed in a table view and as a form label when the field is displayed in a form. You use the DisplayName attribute to change the display name to a value that is different from the name that is defined on the field itself.
