here()

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.

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

here() is very close to self::node()|@* with the single exception that if the current node is a text node, then here() returns the element containing the text node rather than the text node itself.
