John, if you get a parsing error then something in Joomla! is generating mal-formed XML. Even just in the Joomla! core there are a few places where this happens though the main culprits in my experience are 3rd party extensions. This is precisely why people should try to serve proper XHTML so that they catch these bugs as soon as they write them. Perhaps I should have made clearer that this is not something for the average user to play with - you will need to be able to modify a few bits of code to work around the various issues with your site not producing valid XHTML in places. There's not much point in me starting to write up examples/tutorials in relation to this until I've finished the work I'm doing right now to fix all the XHTML issues in the Joomla! core. I tried posting in the forums to get the Joomla! core developers involved, but nobody seems interested, so I'm not sure yet what form a more complete solution will need to take. I might just maintain my own Joomla! branch somewhere as a 100% XHTML compliant version and start checking the most popular extensions for XHTML compliance. Unfortunately I'm a little short on time for this particular project right now...
