Assigns a generated ID to the selected element.

The type of generated ID is based on the option selected in the DITA Options dialog. The ID type “GUID” is a standard globally unique identifier, and the ID type “QUID” is a quasi-unique identifier.

The QUID value is based on the current date and time (composed from values representing the year, month, day, hours, minutes, seconds, plus two randomly generated values). It is designed to be unique per user for 100 years. You can specify an ID prefix in the Options dialog. If you specify a unique ID prefix for each user, the generated IDs will be unique for each member of your team.
