If you understand the processing model of XSLT, whereby processing begins
at the root node and from there everything that happens is a result of
processing templates (some of which may be built-in as prescribed by the
spec), then it should be apparent that the authors of this XSLT document
are simply overriding the built-in template for all elements.

Why would they want to do this? Perhaps because they know that the XML
schema may change, and they don't want any new, unaccounted-for element
types that don't have explicitly matching templates of their own to be
processed by the built-in template.
