Yes / No (Boolean)

Description

The Yes/No datatype is used as Boolean (True/False) and has 2 specific values (Yes/True or No/False) besides the Unknown situation (which is not really a specific value), and is mostly used for conditional statements. When a YesNo field-value is displayed on a page, it will - based on the current language - display Yes or No or nothing when the situation is Unknown. In Expressions the True and False equivalents are implicated; Unknown should be regarded specifically if that situation may occur (check the If-Unknown operator)

• True

An unknown value can be written as UnknownBoolean.
