Consider a simple slide show. In this example,
here()/following::SLIDE[1]
refers to the next slide in the
show. here()/preceding::SLIDE[1]
refers to the previous slide
in the show. Presumably this would be used in conjunction with a
style sheet that showed one slide at a time.
<?xml version="1.0"?>
<SLIDESHOW xmlns:xlink="http://www.w3.org/1999/xlink">

Generally, the here()
location term is only used in fully
relative URIs in XLinks. If any URI part is included, it must be
the same as the URI of the current document.
