Please extend the field definition to hold a text attribute with the help information on the field. This is used to inform the user about the use of the field when looking at an asset detail page.
The "HelpInfo" attribute should work similar as it works for the ErrorMessage on the validation: containing a text value, or a reference so we can use the translations to show translated info.
On the asset detail page, for every field having a value in the HelpInfo, it should show an "Info" icon next to the label. When hovering or clicking the icon, the content of the HelpInfo attribute should be shown.
