Before you start generating, create three layouts and name
them so that you know what each contains. For example use the tag
names in your scenario so one output for administrator, one for
super user and one for user. Then in each set the required build
expression and point each one to a different folder.
The ability to apply tags to a folder and book came in RH6.
It enables you to apply the tag to all but you have to remove
individually. Also you have to apply it to subsequently added
topics in the folder book.
Empty books should not appear if all the topics have been
excluded, at least, to the best of my recollection.
