A pop-up list is used in the Text tab of Document Settings to set the default format used for Date-type attributes in note Displayed Attributes. There are 3 values.
- Locale 'long' date with time.
- Locale 'long' date only.
- Locale 'short' date only.
The values shown are for a UK locale ('en-GB'). The strings actually seen will vary according to the user's locale.
