Thanks, I considered this, but I think that passing the full XPath
makes debugging easier and will be more robust if I change the source
XML (it has a chance of still working, instead of being guaranteed not
to work.)

As for easier debugging when using XPath expressions, this is right,
but only in the case we know well the source xml document. In case the
transformation is designed to be generic and process *any* source xml
document, then in the general case when the structure of the source xml
is not known to the programmer, using XPath expressions is exactly as
helpful as using another uid system.

The big advantage of the coordinate uid method is the fact that nodes
can be located very fast by using a key. Future XSLT processors could
be optimised to automatically maintain the coordinate uid of every
node, so that a programmer would not even have to declare an xsl:key
for node() on its coordinates.
