\subsection pf_tag_zone <zone>
-For historical reasons, the XML files use the expression AS for
-NetZones. Netzones are very important because they group other resources (such
-as routers/hosts) together (in fact, any such resource must be
-contained in a NetZone).
+Before SimGrid v3.16, networking zones used to be called Autonomous
+Systems, but this was misleading as zones may include other zones in a
+hierarchical manner. If you find any remaining reference to ASes,
+please report this as a bug.
