Input type has to be the same as the current setting type, output type has to be a boolean.

For now the easiest way to create a new UvP string is to create one in HpD Studio GUI and then read and copy it in API.

This property is enabled only if DisplayCondition is true.

This property is disabled when current decoration is not attached to a parent setting as the input depends on the attached setting type.
