The above is a *relatively simple* and quite self-explaining XPath
expression. If you need an example of a really *complex* one, do have a
look at:

This only *looks* simple, because from the seven types of nodes you're
using only the element type. Add to this the potential of having some
additional predicates attached...

Another problem is that this will result in mixing two considerably
different approaches for specifying node-sets of a tree.

In XPath/XSLT 2.0 this is unnecessary, because one has access to the
PSVI type annotations -- am I correct, ver. 2 gurus?
