I had a problem similar to this where I needed to write the XML stream
out, but I also needed this sort of log as well. In my case I was trying
to make a list of all the graphics and create a batch file that would copy
the files from a common area (lots of unused graphics here) and move the
files I needed to an area I would use for delivery.

I used the <xsl:message> to write these to stdout, I sent that to a file
by piping the output, or just cut and pasted the messages into another

Now this makes it hard to write debugging statements, but it saved me from
creating another stylesheet for just this purpose.

It would have been nice to just have the ability to write to a file as
needed from within the stylesheet; that would have been a cleaner
approach, but this satisfied my needs at the moment.
