XML use in documentation: examples sought

[admin]

I manage a group of tech writers producing system documentation that we deployin HTML over a corporate intranet. I have been hearing XML buzz for longenough now that I'm finally looking into its usefulness for producing andmaintaining documentation. It's easy to find citations that say XML is niftyand cool and will solve all problems, but I have yet to see a document producedusing XML so that I could evaluate what benefits XML brings to the party.Can anyone point me to a place (presumably a Web site) that consists largelyof -- or at least contains -- significant documentation created using XML?Thanks.Philip JonesPhiladelphia PA
