<!-- apply-templates for each item in the list.
     Normally, those items are id of nodes.
     Those nodes can be sect1 (normal case),
     sect2 (python modules or DBus bindings)
     bridgehead (perl modules)
     para (dependency of perl modules).
     The templates after this one treat each of those cases.
     However, some items are xorg package names, and not id.
     We need special instructions in that case.
     The difficulty is that some of those names *are* id's,
     because they are referenced in the index.
     Hopefully, none of those id's are sect{1,2}, bridgehead or para...-->
