This approach does have a slight disadvantage: the navigation aids must be
reproduced on the places they link to, meaning

1) If they contain lots of images, etc., it takes longer to download the
page linked to.

2) Any change to the navigation aids must be made to several different
documents, unless they are embedded, which would would defeat the object.
