The Family Name of the target. This will be used in conjunction with the Given Name to make up the full name of the Target as it is listed in the contents view and Target Selection list in an Action Edition.
The default label is 'Family Name' so that it is applicably globally, including:
- Places where the 'Family Name' is written first and thus is the 'First Name' (e.g. Chinese names)
- Places where people have more than one 'Family Name' (e.g. Spanish names)
